Here is the TCS codevita 2016 Questions. These questions are somewhat new and mind twisting. Each question takes lots of time to solve. Here are the questions.
TCS codevita 2016 Problem 1: Logic Pyramid
Identify the logic behind the series
6 28 66 120 190 276…..
The numbers in the series should be used to create a Pyramid. The base of the Pyramid will be the widest and will start converging towards the top where there will only be one element. Each successive layer will have one number less than that on the layer below it. The width of the Pyramid is specified by an input parameter N. In other words there will be N numbers on the bottom layer of the pyramid.
TCS codevita 2016 Problems 
The Pyramid construction rules are as follows
 First number in the series should be at the top of the Pyramid
 Last N number of the series should be on the bottommost layer of the Pyramid, with Nth number being the rightmost number of this layer.
 Numbers less than 5digits must be padded with zeroes to maintain the sanctity of a Pyramid when printed. Have a look at the examples below to get a pictorial understanding of what this rule actually means.
Example
If input is 2, output will be
00006
00028 00066
If input is 3, output will be
00006
00028 00066
00120 00190 00276
Formal input and output specifications are stated below
Input Format:
First line of input will contain number N that corresponds to the width of the bottommost layer of the Pyramid
Output Format:
The Pyramid constructed out of numbers in the series as per stated construction rules
Constraints:
 0<N<=14
TCS codevita 2016 Problem 2: Min Product Array
 First line of the input contains n and k delimited by whitespace
 Second line contains the Array A (modifiable array) with its values delimited by spaces
 Third line contains the Array B (nonmodifiable array) with its values delimited by spaces
 Output the minimum sum of products of the two arrays
 1 = N = 10^5
 0 = A[i], B[i] = 10^5
 0 = K = 10^9
Explanations:
Explanation for sample 1:
Here total numbers are 3 and total modifications allowed are 5. So we modified A[2], which is 3 and increased it by 10 (as 5 modifications are allowed). Now final sum will be
(1 * 2) + (2 * 3) + (7 * 5)
2 + 6 – 35
31
31 is our final answer.
Explanation for sample 2:
Here total numbers are 5 and total modifications allowed are 3. So we modified A[1], which is 3 and decreased it by 6 (as 3 modifications are allowed).
Now final sum will be
(2 * 3) + (3 * 4) + (4 * 2) + (5 * 3) + (4 * 2)
6 – 12 + 8 + 15 + 8
25
25 is our final answer.
TCS codevita 2016 Problem 3: Consecutive Prime Sum
Some prime numbers can be expressed as Sum of other consecutive prime numbers.
For example
5 = 2 + 3
17 = 2 + 3 + 5 + 7
41 = 2 + 3 + 5 + 7 + 11 + 13
Your task is to find out how many prime numbers which satisfy this property are present in the range 3 to N subject to a constraint that summation should always start with number 2.
Write code to find out number of prime numbers that satisfy the above mentioned property in a given range.
Input Format:
First line contains a number N
Output Format:
Print the total number of all such prime numbers which are less than or equal to N.
Constraints:
 2<N<=12,000,000,000

TCS codevita 2016 Problem 4 : Bishop Moves
Background
A Chess board position is accurately captured by ForsythEdwards notation and is abbreviated as FEN. A FEN “record” defines a particular game position, all in one text line and using only the ASCII character set. A FEN record contains six fields. A complete description of the FEN format to represent Chess positions can be found at here.
For the purpose of this problem only consider first of the six fields of FEN. Before we describe the problem, let us look at how FEN maps to a board position. The following 5 images show board positions and its corresponding FEN representation.
Figure 1.
This board position depicts initial position before any side has made a move.
In FEN format this board position is represented as
rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w
Let’s say, White plays e4. Then the board position looks like shown below.
Figure 2.
This board position depicts the Chess board after White has played e4.
In FEN format this board position is represented as
rnbqkbnr/pppppppp/8/8/4P3/8/PPPP1PPP/RNBQKBNR b
Similarly, 3 more halfmoves are depicted in following diagrams
Figure 5.
The FENs corresponding to Figure 3, 4 and 5 are represented as(in bold)
3. rnbqkbnr/pppp1ppp/8/4P3/4P3/8/PPPP1PPP/RNBQKBNR w
4. rnbqkbnr/pppp1ppp/8/4p3/4PP2/8/PPPP2PP/RNBQKBNR b
5. rnbqkbnr/pppp1ppp/8/8/4Pp2/8/PPPP2PP/RNBQKBNR w
Wikipedia describes first field of FEN format as follows
Each rank is described, starting with rank 8 and ending with rank 1; within each rank, the contents of each square are described from file “a” through file “h”. Following the Standard Algebraic Notation (SAN), each piece is identified by a single letter taken from the standard English names (pawn = “P”, knight = “N”, bishop = “B”, rook = “R”, queen = “Q” and king = “K”).[1] White pieces are designated using uppercase letters (“PNBRQK”) while black pieces use lowercase (“pnbrqk”). Empty squares are noted using digits 1 through 8 (the number of empty squares), and “/” separates ranks.
The second field denotes whose move it is now. “w” depicts that it is White’s turn to play and “b” indicates that it is Black’s turn to play
CodeVita Problem Statement
Given a board position in FEN format, your task is to find out all the move(s) that Bishop(s) of the playing side can make.
Input Format:
 First line contains single FEN record, which corresponds to a particular board position and also indicates whose turn it is.
Output Format:
 The output must be printed as follows
 All legal moves that Bishop can make must be in the format “[<Move Format>]”
 Where <Move Format> is move represented in format “[fromSquare][toSquare]“
 See Example section for better understanding of output format.
 Follow Output printing specification to print the output in required format.
Constraints:
 Since we focus on only first two parts of the FEN, we are essentially ignoring possibility of Castling. Hence our test cases don’t contain FENs which give rise to such positions.
Sample Input and Output
Sample 1 input: 3k4/8/8/2P1P3/3B4/2R1R3/8/4K3 w
Board Depiction 1:
Output 1: []
Sample 2 input: 3k4/8/8/2P1P3/3B4/2R1R3/8/4K3 w
Board Depiction 2:
Output 2: [d4a7, d4b6, d4c5]
Sample 3 input: 3k4/8/8/2P1P3/3B4/2R1R3/8/4K3 w
Board Depiction 3:
Output 3: [d4h8, d4a7, d4g7, d4b6, d4f6, d4c5, d4e5, d4c3, d4e3, d4b2, d4f2, d4a1, d4g1, b1h7, b1g6, b1f5, b1e4, b1d3, b1a2, b1c2]
Print Specification:
 Should start with “[” and end with “]”
 If more than one move is possible, moves should be separated by a comma followed by whitespace
 Moves of a single bishop should be printed in Move Format. Scan the board from 8th rank to 1st rank from afile to hfile. Whichever square gets hit first, that move should be printed first.
 If more than one bishop exists for side to move, then start scanning for bishop from 8th rank to 1st rank, left to right i.e. from afile to hfile. Whichever bishop appears first, print all moves for that bishop first.
 Verify your understanding of how printing should happen against examples shown above
TCS codevita 2016 Problem 5 : Continents and Oceans
There will be several continents on a world map. Idea is to identify the number of continents and the mass in each.
The land is denoted by ‘#’ and ocean by spaces. You have to find the number of continents (connected masses of land) and print the number of # in the continent.
Connected mass of land means that # can be connected in any way i.e. horizontally, vertically or diagonally.
Input Format:
 Path to a file, for example /tmp/T1.txt
 This file contains 15 rows and 60 columns depicting a map. See Examples section below.
Output Format:
Number of # per continent in descending order of size and total number of continents in the format depicted below
Island 1: <Biggest mass> say 100
Island 2: <Smallest mass> say 50
Number of continents: 2
Output:
Island 1: 593
Island 2: 98
Number of continents: 2
So Output is:
Island 1: 593
Island 2: 98
Number of continents: 2
Output:
Island 1: 805
Island 2: 68
Number of continents: 2
TCS codevita 2016 Problem 6 : Football League Table
Statement :
All major football leagues have big league tables. Whenever a new match is played, the league table is updated to show the current rankings (based on Scores, Goals For (GF), Goals Against (GA)). Given the results of a few matches among teams, write a program to print all the names of the teams in ascending order (Leader at the top and Laggard at the bottom) based on their rankings.
Rules: :
 A win results in 2 points, a draw results in 1 point and a loss is worth 0 points.
 The team with most goals in a match wins the match.
 Goal Difference (GD) is calculated as Goals For (GF) – Goals Against (GA).
 Teams can play maximum of two matches against each other – Home and Away matches respectively
 Ranking is decided as follows
 Team with maximum points is ranked 1 and minimum points is placed last
 Ties are broken as follows
 Teams with same points are ranked according to Goal Difference(GD).
 If Goal Difference(GD) is same, then team with higher Goals For is ranked ahead
 If GF are same, the teams should be at the same rank but they should be printed in caseinsensitive alphabetic according of the team names.
 More than 2 matches of same teams, should be considered as Invalid Input
 A team can’t play matches against itself, hence if team names are same for a given match, it should be considered Invalid Input
Input Format:
 First line of input will contain number of teams (N)
 Second line contains names of the teams (Na) delimited by a whitespace character
 Third line contains number of matches (M) for which results are available
 Next M lines contain a match information tuple {T1 T2 S1 S2}, where tuple is comprised of the following information
• T1 – Name of the first team
• T2 – Name of the second team
• S1 – Goals scored by the first team
• S2 – Goals scored by the second team
Output Format:
Team names in order of their rankings, one team per line
OR
Print “Invalid Input” where appropriate.
Constraints:
 0<N<=10,000
 0<=S1,S2
Example:
Consider 5 teams Spain, England, France, Italy and Germany with the following fixtures:
Match 1: Spain vs. England (30)
(Spain gets 2 points, England gets 0)
Match 2: England vs. France (11)
(England gets 1 point, France gets 1)
Match 3: Spain vs. France (02)
(Spain gets 0 points, France gets 2)
Table 1. Points Table after 3 matches 
Since, Italy and Germany are tied for points, goals difference is checked. Both have same, so, Goals For is checked. Since both are same. Germany and Italy share the 4th rank. Since Germany appears alphabetically before Italy, Germany should be printed before Italy.
Then the final result is:
France
Spain
England
Germany
Italy
TCS codevita 2016 Problem 7 : Mate In One
Background
A Chess board position is accurately captured by ForsythEdwards notation and is abbreviated as FEN. A FEN “record” defines a particular game position, all in one line of text and using only the ASCII character set. A FEN record consists of six fields. A complete description of the FEN format to represent Chess positions can be found here.
For the purpose of this problem, only consider first of the six fields of FEN. Before we describe the problem, let us look at how FEN maps to a board position. The following 5 images show board positions and its corresponding FEN representation.
Figure 1 
This board position (above) depicts initial position before any side has made a move. In FEN format this board position is represented as
rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR
Let’s say, White plays e4. Then the board position looks like shown below.
figure 2 
This board position (above) depicts the Chessboard after White has played e4. In FEN format this board position is represented as
rnbqkbnr/pppppppp/8/8/4P3/8/PPPP1PPP/RNBQKBNR
figure 3 
figure 4 
figure 5 
 First line contains single FEN record, which corresponds to a particular board position
 Second line contains 1 which indicates the end of input
 The output must be printed as follows
 A string “Mating moves ” followed by “[<move format>]”
 Where <move format> is move represented in format “[Piece][fromSquare][Piece][toSquare]”
 If a mating move involves a capture then represent it as “[Piece][fromSquare][Piece]x[toSquare]”
 If the Piece inflicting a mate is a pawn represent it only as [fromSquare][toSquare]
 If there is more than one mating move, then follow the rules given below
 Moves must be sorted alphabetically according to their ascii values
 Two moves must be separated by a comma followed by a white space characters
 Between the last move and terminating “]” character there should be no space or comma
2. See Example section for better understanding of output format
 The board position will always be White to move and mate in 1
 Since we focus on only first part of the FEN, we are essentially ignoring possibility of Castling being a mating move. Hence our test cases don’t contain FENs which give rise to such positions.
 There is no need to handle En Passant positions. There are no test cases involving En Passant moves.
 No need to implement pawn promotion rules. Our test cases do not contain positions which will lead to a pawn getting promoted and inflicting a mate.
 There are no test cases in which capture by a white pawn leads to a mate.
SNo.

TCS codevita 2016 Problems 8: Where’s my car!
The year is 2050. The population surge has taken over our metropolitan cities. High rise buildings are on a rise. And as usual, with the increase in population, the problem of parking in the city has increased manifold.
To reduce the problem of parking, the government has built multistorey parking lots all over the city. Imagine the city as an XY grid. And there are roads connecting all the neighbouring grid points except diagonals. And there is a predefined intersection interval ‘I’ for parking lots such that at every I th intersection, there is a parking lot, starting from (0,0). For example, for a city of grid size 4×7 and I=3, you’ll have 6 parking lots at (0,0), (0,3), (0,6), (3,0), (3,3) and (3,6).
Now all the cars have been fitted with selfdriving mechanism. So whenever you get out of a car at any point in the grid, it will choose the nearest parking lot and automatically drive to it. If two parking lots are at equal distance from where you left, it will choose the parking lot with the lowest Xcoordinate first, and if Xcoordinates are same, the lowest Ycoordinate.
At the parking lot, the cars will start getting parked from the ground floor and in the first available slot. As each floor gets filled up, newer cars will start parking on floors above them. Assume all the parking lots in the city have unlimited number of floors and a common maximum capacity of each floor ‘C’.
Now whenever the owner wants to know where his car is parked or wants to retrieve it, he’ll open the app ‘Where’s my car!’ and insert his car number and the app will tell him the coordinates of the parking lot, the floor number and the slot number.
Input Format:
The first line will contain a positive integer T determining the number of test cases.
For each test case, the first line will contain four positive integers X, Y, I and C, delimited by space where,
 X,Y denote the grid size of the city,
 I denotes the intersection interval for parking lots
 C denotes the maximum capacity of a floor in all the parking lots in the city.
The next line will contain a positive integer N denoting the number of events following.
 An event can be parking of a car(P) or retrieval of a car(R ).
 The next N lines will begin with either a character ‘P’ or ‘R’.
 If the line begins with P, it will also contain two positive integers, x and y denoting the current coordinate of the car where it is left off and has to drive itself to the nearest parking lot, and the car number S which is a unique 10digit number for each car and can contain a mix of numbers and alphabet.
 If the line begins with ‘R’, it will contain the car number to retrieve.
Output Format:
For each test case, output the following.
First output the total number of parking lots in the city.
Then, for every retrieval event in the input list, output 4 space separated integers, p,q,r,s where
 p,q is the coordinate of the parking lot where the car is parked in,
 r is the floor number and s is the slot number.
 For brevity, output each number p,q,r,s, modulo 10.
Constraints:
 11<=T<=10
 1<= X,Y < 2,000,000,000
 1<= C,N < 100,000
 1<= I <= X,Y
 0<= p <= X
 0<= q <= Y
 Max no. of parking lots < 1,000,000

Chirag is a pure Desi boy. And his one and only dream is to meet Santa Claus. He decided to decorate a Christmas tree for Santa on coming Christmas. Chirag made an interesting Christmas tree that grows day by day.
The Christmas tree is comprised of the following Parts:
 Stand
 Each Part is further comprised of Branches.
 Branches are comprised of Leaves.
How the tree appears as a function of days should be understood. Basis that print the tree as it appears on the given day. Below are the rules that govern how the tree appears on a given day. Write a program to generate such a Christmas tree whose input is number of days.
Rules:
 If tree is one day old you cannot grow. Print a message “You cannot generate christmas tree”
 Tree will die after 20 days; it should give a message “Tree is no more”
 Tree will have one part less than the number of days. E.g. On 2nd day tree will have 1 part and one stand., On 3rd day tree will have 2 parts and one stand On 4th day tree will have 3 parts and one stand and so on.
 Topmost part will be the widest and bottommost part will be the narrowest.
 Difference in number of branches between topmost and second from top will be 2
 Difference in number of branches between second from top and bottommost part will be 1.
