Implement Queue using Stacks - LeetCode

list로 queue 구현 하면 되는 문제.
고민할 게 거의 없었음.

class MyQueue:    

    def __init__(self):
        self.qu = []        

    def push(self, x: int) -> None:
        self.qu.append(x)        

    def pop(self) -> int:
        return self.qu.pop(0)        

    def peek(self) -> int:
        return self.qu[0]        

    def empty(self) -> bool:
        return len(self.qu) == 0
