Create an algorithm that arranges them in order to form the largest possible integer

By | July 2, 2023

Given a list of numbers, create an algorithm that arranges them in order to form the largest possible integer. For example, given [10, 7, 76, 415], you should return 77641510.

Javascript

`function largestNumber(nums) {  nums.sort((a, b) => {    const order1 = String(a) + String(b);    const order2 = String(b) + String(a);    return order2.localeCompare(order1);  });  return nums.join('');}// Example usageconst numbers = [10, 7, 76, 415];const result = largestNumber(numbers);console.log(result);`

Java

`import java.util.Arrays;import java.util.Comparator;public class LargestNumber {    public static String largestNumber(int[] nums) {        String[] numStrings = new String[nums.length];        for (int i = 0; i < nums.length; i++) {            numStrings[i] = String.valueOf(nums[i]);        }        Arrays.sort(numStrings, new Comparator<String>() {            public int compare(String a, String b) {                String order1 = a + b;                String order2 = b + a;                return order2.compareTo(order1);            }        });        if (numStrings[0].equals("0")) {            return "0"; // If the largest number is 0, return "0"        }        StringBuilder result = new StringBuilder();        for (String numString : numStrings) {            result.append(numString);        }        return result.toString();    }    public static void main(String[] args) {        int[] numbers = {10, 7, 76, 415};        String result = largestNumber(numbers);        System.out.println(result);    }}`

Python:

`def largest_number(nums):    nums.sort(key=lambda x: str(x), reverse=True)    largest_int = ''.join(map(str, nums))    return largest_int# Example usagenumbers = [10, 7, 76, 415]result = largest_number(numbers)print(result)`
