- Ans.
Check if binary tree is balanced or not.
A balanced binary tree has the height of left and right subtrees differ by at most 1.
Recursively check the height of left and right subtrees and compare.
Use a helper function to calculate the height of a subtree.
Time complexity: O(nlogn) for a balanced tree, O(n^2) for a skewed tree.
- Q2. Detect loops in linked list.

To detect the start of the loop, reset one pointer to the head and move both pointers at the same pace.
