Q3. Write a program to print primes (I wrote brute force method first, then suggested the n/2 method, then finally the squareroot of n method)
Ans. 
A program to print prime numbers using an efficient algorithm.
• A prime number is greater than 1 and has no divisors other than 1 and itself.

• Brute force method checks all numbers up to n to determine if n is prime.

• Using n/2 method, we only check divisibility up to n/2, reducing iterations.

• The square root method checks divisibility only up to √n, which is more efficient.

• Example: For n=29, check divisibility by 2, 3, 5 (al...read more
