How to pass dynamic html to handy-syntax-highlighter in angular 4? -


i have implemented code highlighter in angular 4 application. tried pass dynamic content handy-syntax-highlighter. not working. displaying first value. html template below.

<handy-syntax-highlighter [language]="'html'" [content]="this.htmlstrin"></handy-syntax-highlighter>

here component code:

export class ngbdmodalcontent implements oninit { @input() name; @viewchild('myform') form;  message :string; htmlstrin : string; contentobj: any;  constructor(public activemodal: ngbactivemodal, private dataservice: dataservice, private renderer: renderer2, private ref:changedetectorref ) { this.htmlstrin = '<div></div>'; }  ngoninit() { }  ngafterviewinit() {}  componentlist = componentlist; showcodewindow = false;  dropdownscomponent(data){     var content = data.html;  (let level1 of content) {   this.htmlstrin = this.generatehtml(level1);   console.log(this.htmlstrin);   (let level2 of level1.html) {     this.htmlstrin +=this.generatehtml(level2);       if(level2.html.length> 0){       (let level3 of level2.html) {         this.htmlstrin += this.generatehtml(level3);         this.htmlstrin = this.htmlstrin.tostring();        }     }           } }

} }

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...
