Tree article Question 1: depth of binary tree Enter a binary tree and find the depth of the tree. The nodes (including root and leaf nodes) passing from root node to leaf node form a path of the tree. The length of the longest path is the depth of the tree, and the depth of the root node is regarded as 1. Data range: the number of nodes ...
