Queue in C++ STL Aqueueis the data structure where the order of elements is important and the queue is maintained asFIFO (First In First Out). Queue operations The basic ADT operations for queue are... EnQueue (int x): to enqueuer an element at therearend ...
The only requirement is that it supports the following operations: front() back() push_back() pop_front() Therefore,the standard container class templates deque and list can be used. By default,if no container class is specified for a particularqueueclass,the standard container class template ...
C++STL--priority_queue(优先队列) priority_queue模版类有三个模版参数,第⼀个是元素类型,第⼆个是容器类型,第三个是⽐较算⼦。其中后两者都可以忽略,默认容器为vector,默认算⼦为less,即⼩的往前排,⼤的往后排(出队列时列尾元素先出队)。 定义priority_queue对象: priority_queue的基本操作与...
Open Compiler #include<iostream>#include<queue>intmain(){std::priority_queue<int>a;a.push(11);a.push(2);a.push(32);while(!a.empty()){std::cout<<"Top element: "<<a.top()<<std::endl;a.pop();}return0;} Output If we run the above code it will generate the following output ...
The queue is an ordered list in which insertions are done at one end (rear) and deletions are done from another end (front). The first element that got inserted is the first one to be deleted (basic principle of FIFO). The main Queue operations are: ...
