We have two integer sequences A and B of the same non-zero length. We are allowed to swap elements A[i] and B[i]. Note that both elements are in the same index position in their respective sequences. At the end of some number of swaps, A and B are b

Given two strings s1, s2, find the lowest ASCII sum of deleted characters to make two strings equal. Example 1: Input: s1 = "sea", s2 = "eat" Output: 231 Explanation: Deleting "s" from "sea" adds the ASCII value of
453. 最小移动次数使数组元素相等 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] class Solution { public int minMoves(int[] nums) { int moves = 0, min = In
Given a non-empty integer array of size n, find the minimum number of moves required to make all array elements equal, where a move is incrementing n - 1 elements by 1. Example: Input: [1,2,3] Output: 3 Explanation: Only three moves are needed (remem

面试时会经常考这样的题目,估计也不让使用正则表达式.还好这个算法还算简单,不过在草稿纸上写难免会出现运行异常,好吧,面试官赢了,乃们屌丝就实实在在的把代码码出来吧. 谢谢“心扉”对我代码bug的纠正,现已想到更简便的方法,思路就是从被匹配字符串a中一个一个往后推,截取b字符串长度的字符串: public class CountHit { public static void main(String[] args) { String a = "123456abcde6a6abc6ab";
