TypeScript数据结构与算法（14）基于LinkedList实现的Set

源码如下：

import { DataStruct_LinkedList } from "../04-Linked-List/DataStruct_LinkedList";
import { Interface_Set } from "../Interface_Set";

export class DataStruct_LinkedList_Set<T> implements Interface_Set<T> {

    private list: DataStruct_LinkedList<T>;

    public constructor() {
        this.list = new DataStruct_LinkedList<T>();
    }


    //不能包含重复元素
    add(e: T): void {
        if (!this.list.contains(e)) {
            this.list.addFirst(e);
        }
    }


    remove(e: T): void {
        this.list.removeElement(e);
    }


    contains(e: T): boolean {
        return this.list.contains(e);
    }


    getSize(): number {
        return this.list.getSize();
    }


    isEmpty(): boolean {
        return this.isEmpty();
    }
}
