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 the d…

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…

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…

用模式的每个字母去当做key对应单词列表的每个字母value, 如果放进dict之前检测到key已经存在,就检测Word[i][j]是否是和已经存在的value一致,不一致就代表不匹配,break检查下一个Word 还有可能不一样的key对应了一样的value,这种情况也要去掉,把dict的value去重一下,比较长度有没有变化,没有变化就代表匹配,最后输出结果. class Solution(object): def findAndReplacePattern(self, words, pat…

To some string S, we will perform some replacement operations that replace groups of letters with new ones (not necessarily the same size). Each replacement operation has 3 parameters: a starting index i, a source word x and a target word y.  The rul…

1 我们查看源代码之后获得的网页文件如下图所示,一般都是href="/p-286018571.html"我们只要能提取到所有的"/p-XXXXXXXX.html"这样的东西,至于前面的http://www.docin.com则可以手动批量添加,甚至后面的.html也可以手动添加,我们只要得到一串数字就可以了.我们最终希望的是能够获取如下面的这种网址列表,最笨的办法就相当于我们一个一个点击打开,然后到IE地址栏去复制粘贴一样.当然这里我们讲如何使用软件提高效率. ht…
