Implement the following operations of a queue using stacks. push(x) -- Push element x to the back of queue. pop() -- Removes the element from in front of queue. peek() -- Get the front element. empty() -- Return whether the queue is empty. Example: MyQueue queue = new MyQueue(...
Leetcode 232 Implement Queue using Stacks 和 231 Power of Two,1.232ImplementQueueusingStacks1.1问题描写叙述使用栈模拟实现队列。模拟实现例如以下操作:push(x).将元素x放入队尾。pop().移除队首元素。peek().获取队首元素。empty().推断队列是否为空。注意:仅仅能
Implement Queue using Stacks 解题报告:这个就是考虑Queue 和 Stack的输入输出数据结构的不同, 我看LeetCode上还有大神直接用peek peek就完事了的, 我这个就是比较笨的方法。 首先确定要有两个stack存数据, 我是设定一个stack 存有所有的数据, 基本上这个stack 就是个queue 。 再回来考虑queue和stack 的区别, ...
