Obtaining maximum number via rotating digits in JavaScript
Problem
We are required to write a JavaScript function that takes in a positive integer n and returns the maximum number we got doing only left rotations to the digits of the number.
Example
Following is the code −
const num = 56789;
const findMaximum = (num = 1) => {
let splitNumbers = num.toString().split("");
let largestNumber = num;
for(let i = 0; i < splitNumbers.length - 1; i++) {
splitNumbers.push(splitNumbers.splice(i, 1)[0]);
let newNumber = Number(splitNumbers.join(""));
if(newNumber >= largestNumber) {
largestNumber = newNumber;
}
};
return largestNumber;
};
console.log(findMaximum(num));Output
