Return the difference between the maximum & minimum number formed out of the number n in JavaScript

Javascript Web Development Object Oriented Programming

We have to write a function maximumDifference() that takes in a positive number n and returns the difference between the maximum number and the minimum number that can be formed out of the number n.

For example −

If the number n is 203,

The maximum number that can be formed from its digits will be 320
The minimum number that can be formed from its digits will be 23 (placing the zero at one’s place)

And the difference will be −

320-23 = 297

Therefore, the output should be 297

Let's write the code for this function −

Example

const digitDifference = num => {
   const asc = +String(num).split("").sort((a, b) => {
      return (+a) - (+b);
   }).join("");
   const des = +String(num).split("").sort((a, b) => {
      return (+b) - (+a);
   }).join("");
   return des - asc;
};
console.log(digitDifference(203));
console.log(digitDifference(123));
console.log(digitDifference(546));
console.log(digitDifference(2354));
