Given a pattern and a string str, find if str follows the same pattern. Here follow means a full match, such that there is a bijection between a letter in pattern and a non-empty word in str. Examples: pattern = "abba", str = "dog cat cat d…

Given a pattern and a string str, find if str follows the same pattern. Here follow means a full match, such that there is a bijection between a letter in pattern and a non-empty substring in str. Examples: pattern = "abab", str = "redbluer…

翻译 给定一个模式,和一个字符串str.返回str是否符合同样的模式. 这里的符合意味着全然的匹配,所以这是一个一对多的映射,在pattern中是一个字母.在str中是一个为空的单词. 比如: pattern = "abba". str = "dog cat cat dog" 应该返回真. pattern = "abba", str = "dog cat cat fish" 应该返回假. pattern = "aaa…

290. Word Pattern istringstream 是将字符串变成字符串迭代器一样,将字符串流在依次拿出,比较好的是,它不会将空格作为流,这样就实现了字符串的空格切割. C++引入了ostringstream.istringstream.stringstream这三个类,要使用他们创建对象就必须包含sstream.h头文件. istringstream类用于执行C++风格的串流的输入操作. ostringstream类用于执行C风格的串流的输出操作. strstream类同时可以支持…
