std::deque<T,Allocator>::pop_front voidpop_front(); Removes the first element of the container. If there are no elements in the container, the behavior is undefined. Iterators and references to the erased element are invalidated. If the element is the last element in the container, theend...
先使用`std::move`将front元素转换为右值，然后从队列中删除它。这将触发移动构造或赋值，而不是拷贝。

A Stack has two main operations: Push: Pushes an element into the stack Pop: Returns the last element that was put into the stack The Stack's functionality is described as "First in - last out", the first element that...
构建一个堆,默认为大根堆;可以通过自定义的comp来构建小根堆。使用greater<int>()来代替默认的less<int>()来创建heap。 3.1 函数声明 // default (1)template<classRandomAccessIterator>voidmake_heap(RandomAccessIterator first,RandomAccessIterator last)// custom ...
