1 读题 LeetCode 232E 用栈实现队列 Implement Queue using Stacks 2 Python 解题 正如咱们前面那个问题,list 既可以实现栈,还能实现列表,所以咱这题的代码,和那个队列模拟栈的就很类似了。 ## LeetCode 232## Impletement Queue using StackclassMyQueue:def__init__(self):self.l1=[]## stack 1 = l1se...
one of the class reaches a terminating condition. A terminating condition defines thestate at which a recursive function should return instead of making another recursive call. This is basically stack unwinding When the function is called, a stackis allocated to push the function's parameters ...
Learn how to check the maximum sum of all stacks after popping some elements from them using Python with this detailed guide.
class Queue(object): def __init__(self): """ initialize your data structure here. """ self.inStack=[] self.outStack=[] def push(self, x): """ :type x: int :rtype: nothing """ self.inStack.append(x) def pop(self): """ :rtype: nothing """ self.peek() self.outStack....

Python解法 下面的python代码是把stack2当做是和队列顺序一样的,这样的话,如果stack2不空,那么久弹出元素就行。否则,如果stack1中有元素,那么在做push和pop的时候,需要先把stack1中的元素颠倒到stack2中。 AI检测代码解析 class MyQueue(object): def __init__(self): ...
