binary_search() 作为 STL 函数 用法: bool binary_search ( ForwardIterator first, ForwardIterator last, const T& value); 其中, ForwardIterator first= 迭代器到范围的开始 ForwardIterator last=迭代器到范围结束 T &value= 对数据类型为 T 的搜索元素的引用,T 可以是任何内置数据类型或用户定义的数据...

In this article, we are going to learn how to search an element from an array using binary_search() function of C++ Standard Template Library (STL)?

[数据结构]——二叉树(Binary Tree)、二叉搜索树(Binary Search Tree)及其衍生算法 二叉树(Binary Tree)是最简单的树形数据结构,然而却十分精妙。其衍生出各种算法,以致于占据了数据结构的半壁江山。STL中大名顶顶的关联容器——集合(set)、映射(map)便是使用二叉树实现。由于篇幅有限,此处仅作一般介绍(如果想要...
