- Q1. How you find loop in a linked list
- Ans.
To find a loop in a linked list, we use Floyd's cycle-finding algorithm.
Floyd's cycle-finding algorithm uses two pointers, one moving at twice the speed of the other.
If there is a loop in the linked list, the two pointers will eventually meet.
To detect the meeting point, we reset one of the pointers to the head of the linked list and move both pointers at the same speed.
The meeting point is the start of the loop.

- 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.

- Ans.
