Finding the string in range of numbers

Let's say, in the string "91910500", there are numbers (00, 10, 19, 50, 91, 105, 500, 919, 9191, 1910, 1050, 10500, etc...).

You have a range number from 0000000001 to 99999999999. And you have to find a string which contains all the numbers from that range. whatever you guess a number from that range, you will find that number in the main string.

What will be the main string for that range? With the following the code, I still see duplicate in main key. 

var s = "";

for (i = 0; i < 100; i++) {
  console.log('Searching the number ' + i);
  d = i.toString;

  if (s.indexOf(d) >= 0) {} else {
    s = s.concat(i);
  }

  console.log('Key is \n' + s);
}

Your code is almost correct, you just need to update 2 lines:

for (i = 0; i < 100; i++) {

to:

for (i = 100 - 1; i >= 0; i--){

And:

d = i.toString;

to:

d = i.toString();
