如果我们可以将小写字母插入模式串 pattern 得到待查询项 query，那么待查询项与给定模式串匹配。（我们可以在任何位置插入每个字符，也可以插入 0 个字符。） 给定待查询列表 queries，和模式串 pattern，返回由布尔值组成的答案列表 answer。只有在待查项 queries[i] 与模式串 pattern 匹配时， answer[i] 才为 true，否则为 false。   示例 1： 输入：queries = ["FooBar","FooBarTest","FootBall","FrameBuffer"…

Given a string s and a dictionary of strings wordDict, return true if s can be segmented into a space-separated sequence of one or more dictionary words. Note that the same word in the dictionary may be reused multiple times in the segmentation.   Example…

You are given a 0-indexed string s and a dictionary of words dictionary. You have to break s into one or more non-overlapping substrings such that each substring is present in dictionary. There may be some extra characters in s which are not present in any…

给你一个整数数组 nums ，返回 nums[i] XOR nums[j] 的最大运算结果，其中 0 ≤ i ≤ j < n 。   示例 1： 输入：nums = [3,10,5,25,2,8] 输出：28 解释：最大运算结果是 5 XOR 25 = 28. 示例 2： 输入：nums = [14,70,53,83,49,91,36,80,92,51,66,70] 输出：127   提示：
