给定一个长度为 n 的非空整数数组,找到让数组所有元素相等的最小移动次数.每次移动可以使 n - 1 个元素增加 1. 示例: 输入: [1,2,3] 输出: 3 解释: 只需要3次移动(注意每次移动会增加两个元素的值): [1,2,3] => [2,3,3] => [3,4,3] => [4,4,4] 思路 尝试过暴力法 ,结果超时了 找规律 移动次数等于每个数减去最小数之和. Java版 class Solution { public int minMoves(int[] nums)…

一个坐标可以从 -infinity 延伸到 +infinity 的 无限大的 棋盘上,你的 骑士 驻扎在坐标为 [0, 0] 的方格里. 骑士的走法和中国象棋中的马相似,走 “日” 字:即先向左(或右)走 1 格,再向上(或下)走 2 格:或先向左(或右)走 2 格,再向上(或下)走 1 格. 每次移动,他都可以按八个方向之一前进. 现在,骑士需要前去征服坐标为 [x, y] 的部落,请你为他规划路线. 最后返回所需的最小移动次数即可.本题确保答案是一定存在的. 示例 : 输入:x = , y…

公众号: 爱写bug(ID:icodebugs) 给定一个已按照升序排列 的有序数组,找到两个数使得它们相加之和等于目标数. 函数应该返回这两个下标值 index1 和 index2,其中 index1 必须小于 index2. 说明: 返回的下标值(index1 和 index2)不是从零开始的. 你可以假设每个输入只对应唯一的答案,而且你不可以重复使用相同的元素. 示例: 输入: numbers = [2, 7, 11, 15], target = 9 输出: [1,2] 解释: 2 与 7…
