[LeetCode] 706. Design HashMap, Easy

1. 문제

• 내장 라이브러리를 사용하지 않고 요구사항에 맞는 HashTable을 구현하라.

2. 해결

class MyHashMap {
    map:{}
    constructor() {
        this.map = {};
    }

    put(key: number, value: number): void {
        this.map[key] = value;
    }

    get(key: number): number {
        return this.map[key] === undefined ? -1 : this.map[key];
    }

    remove(key: number): void {
        delete this.map[key]
    }
}

/**
 * Your MyHashMap object will be instantiated and called as such:
 * var obj = new MyHashMap()
 * obj.put(key,value)
 * var param_2 = obj.get(key)
 * obj.remove(key)
