Q1. How to find out prime number
Ans. 
Prime numbers are numbers that are only divisible by 1 and themselves.
• Start by checking if the number is less than 2, as prime numbers start from 2.

• Iterate from 2 to the square root of the number and check if the number is divisible by any of these numbers.

• If the number is not divisible by any number in the range, then it is a prime number.
