给你一个由正整数组成的 m x n 矩阵 grid。你的任务是判断是否可以通过 一条水平或一条垂直分割线 将矩阵分割成两部分，使得：

You are given an m x n matrix grid of positive integers. Your task is to determine if it is possible to make either one horizontal or one vertical cut on the grid such that:

给你两个字符串 s1 和 s2 ，两个字符串长度都为 n ，且只包含 小写 英文字母。 你可以对两个字符串中的 任意一个 执行以下操作 任意 次：

You are given two strings s1 and s2, both of length n, consisting of lowercase English letters. You can apply the following operation on any of the two strings any number of times:

机器人在一个无限大小的 XY 网格平面上行走，从点 (0, 0) 处开始出发，面向北方。该机器人可以接收以下三种类型的命令 commands ：

A robot on an infinite XY-plane starts at point (0, 0) facing north. The robot receives an array of integers commands, which represents a sequence of moves that it needs to execute. There are only three possible types of instructions the robot can receive:

给你一个整数数组 nums。 如果满足 nums[i] == nums[j] == nums[k]，且 (i, j, k) 是 3 个 不同 下标，那么三元组 (i, j, k) 被称为 有效三元组 。 有效三元组 的 距离 被定义为 abs(i - j) + abs(j - k) + abs(k - i)，其中 abs(x) 表示 x 的 绝对值 。 返回一个整数，表示 有效三元组 的 最小 可能距离。如果不存在 有效三元组 ，返回 -1。   示例 1： 输入： nums = [1,2,1,1,3]…

You are given an integer array nums. A tuple (i, j, k) of 3 distinct indices is good if nums[i] == nums[j] == nums[k]. The distance of a good tuple is abs(i - j) + abs(j - k) + abs(k - i), where abs(x) denotes the absolute value of x. Return an integer denoting…
