Given the root of a binary tree, return the number of nodes where the value of the node is equal to the sum of the values of its descendants. A descendant of a node x is any node that is on the path from node x to some leaf node. The sum is considered to be 0 if the node ...
Given the root of a complete binary tree, return the number of the nodes in the tree. According to Wikipedia, every level, except possibly the last, is completely filled in a complete binary tree, and all nodes in the last level are as far left as possible. It can have between 1 and...
what do you need to know about the complete binary tree is, let’s assume the root is depth of 0 and the maximum depth is d, so the total number of nodes besides the leaf level will be 2^ (d) - 1, and the number of leaves is in the range of (1, 2^d) and all we need ...

828. Count Unique Characters of All Substrings of a Given String # 题目 # Let’s define a function countUniqueChars(s) that returns the number of unique characters on s, for example if s = "LEETCODE" then "L", "T","C","O","D" are the unique characters
Given a binary tree, count the number of uni-value subtrees. A Uni-value subtree means all nodes of the subtree have the same value. Example Example1 代码语言:javascript 代码运行次数:0 运行 AI代码解释 Input: root = {5,1,5,5,5,#,5} Output: 4 Explanation: 5 / \ 1 5 / \ \ 5...
