Our basic data structure is a FIFO queue, and eachpopcan only take elements in front of the queue; But the stack is FILO, which means thepopAPI takes elements from the rear of the queue. The solution is simple. We can take out the front element of the queue and add...

What is Size Limited Queue in Java? A size-limited queue is a queue with a fixed size of N. It cannot hold elements more than its size. If you try to push more data, it will remove elements from its front end. The Queue is fixed with its size N. ...
Implement Queue using Stacks 链接:https://leetcode.com/problems/implement-queue-using-stacks/ 思路 使用两个栈,stk1用作主要存储。假设已经往stk1里push一些元素,现在要pop,即取栈底的元素,则把上面的元素暂存到stk2里再取栈底。此时把stk2元素放回stk1可恢复原来的顺序,但是,如果下个操作还是pop,此时...
