Design HashMap - LeetCode

오늘은 그냥 딕셔너리를 가지고 해쉬맵 만드는 내용이었다.

class MyHashMap:

    def __init__(self):
        self.d = dict()
        

    def put(self, key: int, value: int) -> None:        
        self.d[key] = value
        

    def get(self, key: int) -> int:
        res = self.d.get(key)
        if res is None:
            return -1
        return res
        

    def remove(self, key: int) -> None:
        if self.d.get(key):
            del self.d[key]
