用法: set_name.find(element) 参数:该函数接受一个强制性参数element ,该元素指定要在集合容器中搜索的元素。 返回值:该函数返回一个迭代器,该迭代器指向在集合容器中搜索的元素。如果找不到该元素,则迭代器将指向集合中最后一个元素之后的位置。 以下示例程序旨在说明上述函数。 // CPP program to dem

cppreference.com 上对于 find 函数的解释是“返回值:指向键等于 key 的元素的迭代器。”,并没有说明到底是哪个元素。 使用Visual Studio 打开头文件 set,找到对应的 find 函数,代码如下(部分): Copy iteratorfind(constkey_type& _Keyval){// find an element in mutable sequence that matches _Keyvaliterator...
Check If the key is less than the element at the m1 index. If yes, then recursively call the function to check if the key is present in between l and m1-1 index. If the key is greater than the element at the m2 index then recursively call the function to check if the key is pre...
