这里使用了find的第一个重载的接口,t为对应的pattern, pos为母串中开始查找的位置。每次查找到一个pattern后,计数,同时跳过pattern的长度,在余下的母串中继续查找。 三、完成题目 这里直接蛮力解决,找出所有的子串,然后调用check_dup_str进行检查,一旦找到第一个满足的情况就退出。 intcheck_dup_str(string&s) {...
在Python中,re模块提供了处理正则表达式的功能。通过该模块,可以进行字符串的查找、匹配、替换等操作。下面是一个简单的示例,演示如何使用re模块查找字符串中的特定模式: importre text="Hello, my phone number is 123-456-7890."pattern=r'\d{3}-\d{3}-\d{4}'result=re.search(pattern,text)ifresult:pr...
