Q1. How to check a number is power of 2
Ans. 
To check if a number is a power of 2, we can use bitwise operations.
• A power of 2 has only one bit set to 1, so we can use the bitwise AND operator to check if the number is a power of 2.

• If n is a power of 2, then n & (n-1) will be 0.

• For example, 8 (1000 in binary) is a power of 2, and 8 & 7 (0111 in binary) is 0.
