Finding difference of greatest and the smallest digit in a number - JavaScript
We are required to write a JavaScript function that takes in a number and returns the difference between the greatest and the smallest digit present in it.
For example: If the number is 5464676, then the smallest digit here is 4 and the greatest is 7
Hence, our output should be 3
Example
Let’s write the code for this function −
const num = 44353456;
const difference = (num, min = Infinity, max = -Infinity) => {
if(num){
const digit = num % 10;
return difference(Math.floor(num / 10), Math.min(digit, min),
Math.max(digit, max));
};
return max - min;
};
console.log(difference(num));Output
The output in the console: −
