Binary search trees have their best performance when they are balanced, which means that at each node, n, the height of the left subtree of n is within 1 of the height of the right subtree of n. Write Give a de

Can you solve this real interview question? Maximum Depth of Binary Tree - Given the root of a binary tree, return its maximum depth. A binary tree's maximum depth is the number of nodes along the longest path from the root node down to the farthest lea
In a binary tree, a maximum of 2L number of nodes can be present at any level L. But, It is very unlikely that each level will have 2L number of elements. There may be a lesser number of elements at any level due to the absence of nodes. For example, The maximum width of the...
