ENTER THE NUMBER TO CHECK : 39
IT IS NOT A PRIME NUMBER.
What we did - Our Approach
In this problem we have to check whether a given number is prime or not.
A prime number is a whole number greater than 1 whose only factors are 1 and itself. A factor is a whole numbers that can be divided evenly into another number. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23 and 29.
For checking a prime number,we ran a for loop from i:2 to n/2,now if our number gets divided by any value of 'i' we set our counter to 1. After the end of the loop , if counter=0 then our number is a prime number else not.
