Boats to Save People . So as an example [1,2,3,4] and [4,3,2,1] are both considered as a valid path, but the path [1,2,4,3] is not a valid one. See your article appearing on the GeeksforGeeks main page and help other Geeks. Diameter of a Binary Tree - GeeksforGeeks; The diameter of a tree (sometimes called the width) is the number of nodes on the longest path between two leaves in the tree. Example: Given a binary tree Given a Binary Tree. leetcode10. Here the path can be either increasing or decreasing. To solve this problem, we need to traverse the binary tree level by level. Given a binary tree, find the length of the longest path where each node in the path has the same value. 34.
