［抄题］: You have a list of words and a pattern, and you want to know which words in words matches the pattern. A word matches the pattern if there exists a permutation of letters p so that after replacing every letter x in the pattern with p(x), we get…

Question 890. Find and Replace Pattern Solution 题目大意:从字符串数组中找到类型匹配的如xyy,xxx 思路: 举例:words = ["abc","deq","mee","aqq","dkd","ccc"], pattern = "abb" abb -> 011 abc -> 012 deq -> 0…

在.net里,使用类Regex可以正则验证一些关键字并取出匹配项. 1.使用Regex.IsMatch(string  input,  string  pattern,  RegexOptions  options)匹配输入字符串与指定的正则表达式是否符合条件: 返回类型:bool true——满足匹配条件  false——不满足匹配条件 input:string类型,输入项 pattern:string类型,指定的正则表达式 options:可选,枚举值,设置正则表达式选项 例:验证字符串中是…

把pattern映射到数字,也就是把pattern标准化. 比如abb和cdd如果都能标准化为011,那么就是同构的. class Solution: def findAndReplacePattern(self, words: List[str], pattern: str) -> List[str]: p = self.get_pattern(pattern) ans = [] for w in words: if self.get_pattern(w) == p: ans.append(w…

题目:给定一个字符串S(主串),一个字符串数组words,其中的字符串的长度相同.找到所有的子串位置,要求是words中字符串的一个连接: 举例: For example, given:s: "barfoothefoobarman"words: ["foo", "bar"] You should return the indices: [0,9]. 解题思路: 1. 采用窗口机制,假设此时每个单词的长度为wordlen; 2.   先将words…

题目描述: 在句子中找出最长的单词,并返回它的长度.函数的返回值应该是一个数字. 基本思路,将字符串转换成数组,然后得出数组中单个元素的长度,对长度进行排序,返回最大的一个 代码: function findLongestWord(str) { // 请把你的代码写在这里 var arr = []; str = str.split(" "); for(var i=0;i<str.length;i++){ arr.push(str[i].length); } arr.sort(fu…
