How to use Array In Javascript
The array is used to select the largest number from the data here. We are creating array names as “temp” that consist of 10 elements initialized to zero, where each of the elements corresponds to the digit [0-9]. Then we are iterating over the input numbers array and incrementing the count of each digit correlation in the “temp” array. There is an empty string, “largestNumber,” that stores the final result. We iterate in the reverse order, from 9 down to 0. For each digit [i], we are checking the count raised in [i]. Then it appends the digit ‘i’ to the largest number, t[i] times, to construct the largest number.
Syntax:
let temp = Array(10).fill(0);
Example: In this example, we will construct the largest number from the digits using the Array.
Javascript
let inputNumbers = [8, 3, 4, 7, 9]; let length = inputNumbers.length; let temp = Array(10).fill(0); for (let i = 0; i < length; i++) { temp[inputNumbers[i]]++; } let largestNumber = ''; for (let i = 9; i >= 0; i--) { while (temp[i]-- > 0) { largestNumber += String(i); } } console.log(largestNumber); |

JavaScript Program to Construct Largest Number from Digits
In this article, we have given a set of digits, and our task is to construct the largest number generated through the combination of these digits. Below is an example for a better understanding of the problem statement.
Example:
Input: arr[] = {4, 9, 2, 5, 0}
Output: Largest Number: 95420
