bodhi tree leaf

Given a binary tree, find all leaves and then remove those leaves. Then repeat the previous steps until the tree was empty.Example:Given binary Tree1/ \2 3/ \4 5Returns [4, 5, 3], [2], [1].Explanation:1. Remove the leaves [4, 5, 3] from the tree1/22. Remove the leaf [2] from the tree13. Remove the leaf [1] from the

Q: Given a binary tree (non-binary search tree), how long is the distance between the two most distant leaf nodes in the binary tree? The distance between the two leaves is defined as f (x, y) = sum of data of all nodes from node X to the Root Node path + sum of data of all nodes from node Y to the Root Node path-from

save Because the NodeA of the node corresponding to the character ' A ' is the root node, i.e. \ (check[t_a]=base[0]=1\) For the leaf node node_leaf, the base address defining the leaf node is begin, the state is T_leaf, code (NODE_LEAF) = 0,Now to prove: check[t_leaf]=t_leaf Begin+code (node_leaf) =t_leaf get: Begin=t_leaf Base[begin+code (node_leaf)]=t_leaf get: Base[begin]=t_leaf

First, the height of the two-fork treeSimilar to the idea of merging sort. The height of the lowest node is first obtained, and then the height of the higher node is compared respectively. Finally, recursion to the root node to find the height of the root node.Find the height of the binary tree int height () {return getheight (_root);} int getheight (nodeSecond, the number of leaf nodes to findRespectively
