输入:s = "ADOBECODEBANC", t = "ABC"输出:"BANC"解释:最小覆盖子串 "BANC" 包含来自字符串 t 的 'A'、'B' 和 'C'。 示例2: 输入:s = "a", t = "a"输出:"a"解释:整个字符串 s 是最小覆盖子串。 示例3: 输入:s = "a", t = "aa"输出:""解释:t 中两个字符 'a' 均应包含在 ...
题目链接 : leetcode-cn.com/problem 题目描述: 给你一个字符串 S、一个字符串 T,请在字符串 S 里面找出:包含 T 所有字母的最小子串。 示例: 输入: S = "ADOBECODEBANC", T = "ABC" 输出: "BANC" 思路: 滑动窗口 我们只要保证窗口(队列)字符串含有t中字符的个数大于等于t里相应元素个数.如方法一...

使用下面描述的算法可以扰乱字符串 s 得到字符串 t : 如果字符串的长度为 1 ,算法停止 如果字符串的长度 > 1 ,执行下述步骤: 在一个随机下标处将字符串分割成两个非空的子字符串。即,如果已知字符串 s ,则可以将其分成两个子字符串 x 和 y ,且满足 s = x + y 。
