STL中关于二分查找的函数有三个lower_bound 、upper_bound 、binary_search 。这三个函数都运用于有序区间（当然这也是运用二分查找的前提），下面记录一下这两个函数。ForwardIter lower_bound(ForwardIter first, ForwardIter last,const _Tp& val)算法返回一个非递减序列[first,

deque双端队列容器与vector很类似，采用线性表顺序存储结构。但与vector区别，deque采用分块的线性存储结构来存储数据，每块的大小一般为512B，将之称为deque块，所有的deque块使用一个map块进行管理，每个map数据项记录各个deque块的首地址，这样的话，deque块在头部和尾部都可以插入和删除。而不需要移动任何元素，而不需要移动其他元素（使用push_back()方法在
