232 implement queue using stacks
232. Implement Queue using Stacks
题目: https://leetcode.com/problems/implement-queue-using-stacks/
难度: Easy
这个题没有乖乖听话，不过因为当年做过用两个stack来模拟queue
然后不得不说，我Python大法实在太厉害了
这功能强大的，我简直要啧啧啧
class Queue(object):
def __init__(self):
"""
initialize your data structure here.
"""
self.lst = []
def push(self, x):
"""
:type x: int
:rtype: nothing
"""
self.lst.append(x)
def pop(self):
"""
:rtype: nothing
"""
del self.lst[0]
def peek(self):
"""
:rtype: int
"""
return self.lst[0]
def empty(self):
"""
:rtype: bool
"""
return self.lst == []
