There are two most important operations of Queue: enQueue:It is operation when we insert element into the queue. deQueue: It is operation when we remove element from the queue. Read also: Queue implementation using LinkedList in java. Java Program to implement Queue using Array: 1 2 3 4 ...
Enqueue:This function is used to add an element to the rear end of the queue. If the queue is completely filled, then it will be in an overflow condition. The time complexity of the enqueue is O(1). Dequeue:This function is used to remove an element from the front end of the queue...
private: //using a static array of size 100. }; Input None Output None Hint Submit your implementation only. 首先简单说明一下queue的用法: back()返回队列最后一个元素引用 empty()是检查是否为空的方法 front()获得队列最前面一个元素引用 push()在队列尾添加一个数据 pop()删除队列头的一个数据 siz...
Queue Implementation using Two Stacks in C++: Here, we are going to implement a C++ program to implement Queue using two Stacks.
Working of queue: We can implement queue by using two pointers i.e. FRONT and REAR. FRONT is used to track the first element of the queue. REAR is used to track the last element of the queue. Initially, we’ll set the values of FRONT and REAR to -1. ...

Given below is a C++ program to understand the string keyword and its usage in an array of strings. #include <iostream> using namespace std; int main() { string numArray[5] = {"one", "two", "three", "four", "five"}; cout<<"String array is as follows:"<<endl; ...
Recently, I was solving the Graphs section of the CSES problemset and encountered this problem. I used dijkstra algorithm to solve it. I generally use the template from here, but in this question, this implementation gave me WA. When I used another implementation using visited array, it gave...
