Count root to leaf paths with equal lengths in a binary tree

geeksforgeeks.org

A binary tree algorithm counts root-to-leaf paths of varying lengths. The program traverses the tree, recording the length of each path to a leaf node in a hash map. It then outputs the counts for each distinct path length found. This approach has a time complexity of O(N) and an auxiliary space complexity of O(log N), where N is the number of nodes in the tree.
