232. Implement Queue using Stacks 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 whet

Implement the following operations of a stack using queues. push(x) -- Push element x onto stack. pop() -- Removes the element on top of the stack. top() -- Get the top element. empty() -- Return whether the stack is empty. Notes: You must use only s

Decode String k[encoded_string] 的编码字符串,将编码的字符重复k次,最后打印出一个完整的字符串. 思路:使用栈结构,由里层向外层,层层解码,当遇到了[ 字符时,向stack当中添加元素,当遇到了]字符时,将stack当中的元素pop() 出来. Q: 重复的数字k如何处理? 用一个 直接用一个命令将字符串复制k次? Q: 如何构建一个新的字符串? String builder ? 原文地址:https://www.cnblogs.com/kong-xy/p/906

翻译 用队列来实现栈的例如以下操作. push(x) -- 将元素x加入进栈 pop() -- 从栈顶移除元素 top() -- 返回栈顶元素 empty() -- 返回栈是否为空 注意: 你必须使用一个仅仅有标准操作的队列. 也就是说,仅仅有push/pop/size/empty等操作是有效的. 队列可能不被原生支持.这取决于你所用的语言. 仅仅要你仅仅是用queue的标准操作,你能够用list或者deque(double-ended queue)来模拟队列. 你能够如果全部的操作都是有效的(
