Finding greatest digit by recursion - JavaScript
We are required to write a JavaScript recursive function that takes in a number and returns the greatest digit in the number.
For example: If the number is −
45654356
Then the return value should be 6
Example
Following is the code −
const num = 45654356;
const greatestDigit = (num = 0, greatest = 0) => {
if(num){
const max = Math.max(num % 10, greatest);
return greatestDigit(Math.floor(num / 10), max);
};
return greatest;
};
console.log(greatestDigit(num));Output
Following is the output in the console −
6
