Sr.No Input Output
1 3, 1,2,3 6
2 3, 10,10,10 30

Problem 2 

Statement: Develop a program to sort the given sequence.(Sort The Sequence)

Program should accept input sequence to be sorted via a file. The file format of the input files is described below. Your program should parse the input file. In case of a bad input, program should output appropriate message as mentioned in output specification below. 

The program should obey the following constraints 
1. The program should detect that inputs are either positive or negative numbers 
2. The program should treat any alphabets or non-numeric characters as invalid inputs 
3. Use double precision data types for handling valid inputs 

File Format: Each element is delimited by a comma. 

Input Format: 
Line 1 Absolute path of the first input file 

Output Format: 
Line 1 For Valid inputs 
Values Before the sort: 
For Invalid inputs 
Invalid Input 
Line 2 Corresponding element of input file where elements are seperated by space 
Line 3 Values after the Ascending sort:

Problem 3 

Statement: Write a program to find Nth prime number in a given range, inclusive of the first and the last element in that range. Program should accept input using commmand line arguments. In case of a bad input, program should output appropriate message as mentioned in output specification below. (Pop Out Primes)

The problem should obey following constraints :
1. Valid range for this problem statement is between 0 and 150000 (One lakh fifty thousand)
2. First element of the range should be less than the last element in the range
3. Prime number index starts from 1

Information: A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself.

Input Format 

Line 1 From Number, say N1
Line 2 To Number, say N2
Line 3 Nth prime number between N1 and N2 where N >=1

Output Format 

Line 1 For Valid inputs
Prime Number at Nth position in a given range,
followed by a new line
For Invalid input
Invalid Input,followed by a new line
OR
No prime number is present at this index,
followed by a new line as is applicable.

Problem 4 

Statement: Develop a program to add two matrices. Program should accept input matrices to be added via files. The file format of the input files is described below. Your program should parse the input files and construct the input matrices. In case of a bad input, program should output appropriate message as mentioned in output specification below. Once the matrices are formed, apply appropriate logic to see if addition is possible. If addition is possible, add the input matrices and output the result in format specified below. (Matrix Addition)

Information: Matrix addition is the operation of adding two matrices that in turn produces resultant third matrix which is a sum of the two input matrices.

File Format
Each row is delimited by newline character
Columns within each row are space delimited
e.g. A 3x3 matrix will be represented in the file as :
1 2 3
4 5 6
7 8 9

Input Format
Line 1 Absolute path of the first input file
Line 2 Absolute path of the second input file

Output
1. Input matrices which are inserted
2. Resultant matrix or appropriate error message in format as mentioned below

Output Format

Problem 5

Statement: Develop a program to find simple interest and compund interest for a given principal amount, rate and tenure. Program should accept the user input using commmand line arguments. In case of a bad input, program should output appropriate message as mentioned in output specification below. (Interest Calculator)

Information: Simple interest is interest paid only on the original principal, not on the interest accrued Simple interest is determined by multiplying the interest rate by the principal by the number of periods. When the interest rate is applied to the original principal and any accumulated interest, this is called compound interest.

Simple interest is calculated using the formula SI=PxNxR
Compound interest is calculated using the formula CI = {[P * (1+(R/100))^N] - P}
where, P = Principal Amount, N=Tenure in years and R=Rate of interest per annum,where N>0 & P>0

Input Format 
Line 1 Principal amount
Line 2 Rate of interest per annum Line 3 Tenure (in years)

Output Format 
Line 1 For Valid input
Simple Interest:
where value is simple interest rounded upto 2 digits
For Invalid input
Invalid Input
Line 2 Compound Interest:
where value is compound interest rounded upto 2 digits,
followed by a new line
