WitrynaTo implement a queue, we can follow two approaches: By making the enqueue operation costly; By making the dequeue operation costly; 1. Making the Enqueue operation costly. In this approach, we make sure that the oldest element added to the queue stays at the top of the stack, the second oldest below it and so on. To achieve … WitrynaWrite a program to implement queue using stack. We should use stack operations like push, pop, top, size, and isEmpty for implementing queue operations like enqueue, dequeue, and front.
