主要是JavaScript在LeetCode上面的 List

This project is convenient for you to debug LeetCode

includes ListNode, TreeNode, Interval, Employee

const node = new ListNode(val) Initialize using an array

(Follow LeetCode topic specifications): ListNode.create(arr : Array) : ListNode

const head = ListNode.create([1, 2, 3, 4, 5]) Visual display

ListNode.prototype.visualShow() : void

const head = ListNode.create([1, 2, 3, 4, 5]) head.visualShow() //1 -> 2 -> 3 -> 4 -> 5 Initialize Cross linked List using arrays

(Follow LeetCode topic specifications, Example Question 160): ListNode.createIntersectList(firstArr: Array<any>,secondArr: Array<any>IntersectArr: Array<any>) : [ListNode, ListNode], parameters are: first ListArray Uncrossed, second ListArray Uncrossed, crossed

const [head1, head2] = ListNode.createIntersectList([1, 2], [3, 4], [5, 6]) Transform ListNodes to array

ListNode.prototype.show() : Array

const head = ListNode.create([1, 2, 3]) head.show() // [1,2,3] ListNode.show(head) // [1,2,3] Get the last ListNode for a ListNode

ListNode.prototype.getLast() : ListNode

const head = ListNode.create([1, 2, 3]) head.getLast().show() // [3] Mock a ListNode with length n

ListNode.mock(n : Number) : ListNode

const head = ListNode.mock(5) Interval Constructor

Interval

const interval = new Interval(1, 3) Initialize using an array

(Follow LeetCode topic specifications): Interval.createList(arr : Array[]) : Interval[]

const intervals = Interval.createList([ [1, 2], [3, 4] ]) Transform Interval to array

Interval.show() : Array

const interval = new Interval(1, 3) interval.show() // [1,3] Interval.show(interval) // [1,3]

Transform Intervals to arrays: Interval.showList() : Array[]

const intervals = Interval.createList([ [1, 2], [3, 4] ]) Interval.showList(intervals) // [[1,2],[3,4]] Employee Constructor

Employee

const employee = new Employee(1)

(Follow LeetCode topic specifications): Employee.createArr(arr: [number, number, number[]][]) : Employee[]

TreeNode

const node = new TreeNode(5) Initialize using an array

(Follow LeetCode topic specifications): TreeNode.create(arr : Array) : TreeNode

P.S. LeetCode title specification is From top to bottom, from left to right, indispensable position fill withnull

const head = TreeNode.create([1, 2, 3, null, 4, null, null, 5, 6]) Transfrom TreeNode to array

TreeNode.prototype.show() : Array

const head = TreeNode.create([1, 2, 3, null, 4, null, null, 5, 6]) head.show() // [1,2,3,null,4,null,null,5,6] TreeNode.show(head) // [1,2,3,null,4,null,null,5,6] Visual display

TreeNode.prototype.visualShow() : void

const head = TreeNode.create([1, 2, 3, null, 4, null, null, 5, 6]) head.visualShow() // 1 -> 2 // ↘→ 4 -> 5 // ↘→ 6 // ↘→ 3 Heap Constructor

Heap

const heap = new Heap([2,1,0,3,4],null,false)

The first argument is inital array The second argument is how to get number from the element, default is null(get the value) For example:

const heap = new Heap([{val: 2, name: 'b'},{val: 1, name: 'a'}], element => element.val, false)

The third parameter indicates whether it is the maximum heap, default is minimum heap

Heap.prototype.add(element: T): number

heap.add(5) delete element

Heap.prototype.delete() : T

head.delete() get the minimum/maximum element

TreeNode.prototype.value[0]

head.value[0] RunScript(For Constructor)

For Question 1172, Dinner Plate Stacks. issue is need For this is Test

Execute input parameters in a certain order function runScript(ommonds: String[], inputs: any[][], classes?: any[]): any[]

// The parameters from left to right are // commonds : List of executed commands // inputs : Corresponding execution parameters // classes : Corresponding execution class array runScript( [ 'DinnerPlates', 'push', 'push', 'push', 'push', 'push', 'popAtStack', 'push', 'push', 'popAtStack', 'popAtStack', 'pop', 'pop', 'pop', 'pop', 'pop' ], [[2], [1], [2], [3], [4], [5], [0], [20], [21], [0], [2], [], [], [], [], []], [DinnerPlates] ) // see example results compare

please use nodejs assert to confirm the result is right.
