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.
Detect loops in a linked list.
Use two pointers, one moving at a faster pace than the other.
If there is a loop, the faster pointer will eventually catch up to the slower one.
To detect the start of the loop, reset one pointer to the head and move both pointers at the same pace.
