arrays - Working with types in typescript -


i declare object has following structure

public car = {     price: 20000,     currency: eur,     seller: null,     model: {         color: null,         type: null,         year: null     } array<object> };

then, when work object, have like

public addproduct(typeid: number): void {     this.car.model.push({type: typeid}); }

the problem facing when defined model object, using as array<object> generates alone lines

type '{ color: null; type: null; year: null; }' cannot converted type 'object[]'. property 'length' missing in type '{ color: null; type: null; year: null; }

i couldn't find proper why define this. important use push generate "empty" object can add attributes view.

you can create object in typescript 

let car: = {   price: 20000,   currency: 'eur',   seller: null,   model: [     { color: 'red', type: 'one', year: '2000' },      { color: 'blue', type: 'two', year: '2001' }   ] }

then can wanted 

car.model.push({ color: 'green', type: 'three', year: '2002' });

to add new model, or fetch one

car.model[0] // returns { color: 'red', type: 'one', year: '2000' }

another alternative create class instead of object

export class car {   public price: number;   public currency: string;   public seller: string;   public models: any[];    constructor() { } }

and put appropriate methods inside class.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
