题目地址:https://leetcode-cn.com/problems/string-matching-in-an-array/ 题目描述 给你一个字符串数组words,数组中的每个字符串都可以看作是一个单词。请你按 任意 顺序返回words中是其他单词的子字符串的所有单词。 如果你可以删除words[j]最左侧和/或最右侧的若干字符得到word[i],那么字符串words[i]就是...
Example 2: Input: words = ["leetcode","et","code"] Output: ["et","code"] Explanation: "et", "code" are substring of "leetcode". Example 3: Input: words = ["blue","green","bu"] Output: [] Constraints: 1 <= words.length <= 100 1 <= words[i].length <= 30 words[i]c...

“When you see string problem that is about subsequence or matching, dynamic programming method should come to your mind naturally. ” 所以这道题还是用DP的思想解决。 大体思路是,s1取一部分s2取一部分,最后是否能匹配s3。 动态规划数组是dp[i][j],表示:s1取前i位,s2取前j位,是否能组成s3的前i+...
Output:"cbad" Explanation:"a","b","c"appear in order, so the order of"a","b","c"should be"c","b", and"a". Since"d"does not appear inorder, it can be at any position in the returned string."dcba","cdba","cbda"are also valid outputs. ...
For the purpose of this problem, we define empty string as valid palindrome. \subsubsection{分析} 无 \subsubsection{代码} \begin{Code} // Leet Code, Valid Palindrome // 时间复杂度O(n),空间复杂度O(1) class Solution { public: bool isPalindrome(string s) { transform(s.begin(), s.end...
我们通常想到的string matching against一个string set的方法是给string set建立trie。这道题不能直接用这种方法,因为我们要求edit distance为1。实际上,edit distance为1就是允许trie里的string有1个字符和输入字符不匹配。这种不匹配既可以是字典里的词多了一个letter,可以是输入的string多了一个letter,也可以是这两...

Problem: Given a set of keywords words and a string S, make all appearances of all keywords in S bold. Any letters between and tags become bold. The returned string should use the least number of tags possible, and of course the tags should form a valid combination. For example, given ...
