다음은 LinkedList 클래스의 완전한 구현입니다.
예시
class LinkedList {
constructor() {
this.head = null;
this.length = 0;
}
insert(data, position = this.length) {
let node = new this.Node(data);
if (this.head === null) {
this.head = node;
this.length++;
return this.head;
}
let iter = 1;
let currNode = this.head;
while (currNode.next != null && iter < position) {
currNode = currNode.next;
iter++;
}
node.next = currNode.next;
currNode.next = node;
this.length++;
return node;
}
remove(data, position = 0) {
if (this.length === 0) {
console.log("List is already empty");
return;
}
this.length--;
let currNode = this.head;
if (position <= 0) {
this.head = this.head.next;
}
else if (position >= this.length - 1) {
while (currNode.next.next != null) {
currNode = currNode.next;
}
currNode.next = null;
}
else {
let iter = 0; while (iter < position) {
currNode = currNode.next; iter++;
}
currNode.next = currNode.next.next;
}
return currNode;
}
display() {
let currNode = this.head;
while (currNode != null) {
console.log(currNode.data + " -> ");
currNode = currNode.next;
}
}
}
LinkedList.prototype.Node = class {
constructor(data) {
this.data = data;
this.next = null;
}
};
