题目: Given a binary tree, find the maximum path sum. For this problem, a path is defined as any sequence of nodes from some starting node to any node in the tree along the parent-child connection
题目翻译 给定一个 n n n,寻找一个 x x x 使得: 2 ≤ x ≤ n 2\le x\le n 2≤x≤n。所有小于等于 n n n 的 x x x 的倍数的和最大。 输出这个 x x x。 本题每个样例有 t t t 组测试数据。 思路 对于这道题,可以枚举 x x x 的值,找到符合要求的 x x x。 显然,对于每一个 x x x 直接暴力累加倍数

Question: Given a binary tree, find its maximum depth. The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node. 找二叉树的最大深度 Algorithm:
index column size too large. the maximum column size is 767 bytes 报错主要出在mysql5.6版本和MariaDB10 1.检查配置文件 my.cnf 检查这3条配置文件,没有就添加上innodb_large_prefix = 1innodb_file_per_table = 1innodb_file_format
Problem Description Let’s start with a very classical problem. Given an array a[1…n] of positive numbers, if the value of each element in the array is distinct, how to find the maximum element in
