C++ Queues(队列)、Priority Queues(优先队列) C++ Queues(队列) C++队列是一种容器适配器,它给予程序员一种先进先出(FIFO)的数据结构。 1.back() 返回一个引用,指向最后一个元素 2.empty() 如果队列空则返回真 3.front() 返回第一个元素 4.pop() 删除第一个元素 5.push() 在末尾加入一个元素 6.size...
C++ Priority Queues empty 语法: bool empty(); empty()函数返回真(true)如果优先队列为空,否则返回假(false)。 pop 语法: void pop(); pop()函数删除优先队列中的第一个元素。 push 语法: void push( const TYPE &val ); push()函数添加一个元素到优先队列中,值为val。 size 语法: size_type size(...

Priority queues are a type of container adapters, specifically designed such that the first element of the queue is the greatest of all elements in the queue and elements are in non decreasing order(hence we can see that each element of the queue has a priority{fixed order}). The functions...
3. What does the swap function do in the context of priority queues? A. It merges two queues B. It exchanges elements between two queues C. It clears the queue D. It sorts the queue Show Answer 4. How are elements ordered in a priority queue by default? A. In ascending orde...
