// CPP code to illustrate Queue operations in STL // Divyansh Mishra --> divyanshmishra101010 #include <iostream> #include <queue> using namespace std; // Print the queue void print_queue(queue<int> q)
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...

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: ...
This function is commonly used in conjunction with push(), pop() and empty() for managing queue operations. The time complexity of this function is constant O(1).When we try to invoke the front() function on the empty queue it results in the undefined behaviour....
