Problem Description

Given an integer n. No-Zero integer is a positive integer which doesn't contain any 0 in its decimal representation.

Return a list of two integers [A, B] where:

A and B are No-Zero integers.
A + B = n

It's guarateed that there is at least one valid solution.

If there are many valid solutions you can return any of them.

Solution

/**
 * @param {number} n
 * @return {number[]}
 */
var getNoZeroIntegers = function(n) {
  const hasNoZero = n => String(n).indexOf('0') === -1;
  for (let i = n; i; --i) {
    if (hasNoZero(i) && hasNoZero(n - i)) {
      return [i, n - i];
    }
  }
};
