Largest 5 digit number in a series

Largest 5 digit number in a seriesCodewars

Approach

1. convert as string and split it as array

2. iterate from begin to length-4

   1. convert as number between [index, index+4]

   2. if process 2-1 is bigger than max num change max num

3. return max num

Solution

JavaScript

const solution = (digits) => {
  const numbers = [...String(digits)];
  let max = 0;
  let currentNum = 0;
  
  for (let i = 0; i < numbers.length - 4; i += 1) {
    currentNum = Number(numbers.slice(i, i + 5).join(''));
    if (currentNum > max) {
      max = currentNum;
    }
  }
  
  return max;
};
