/**
 * @param {number} num
 * @return {number}
 */
var minimumSum = function (num) {
  const numToArr = num.toString().split('');

  for (let i = 1; i < numToArr.length; i++) {
    for (let j = 0; j < i; j++) {
      if (numToArr[i] < numToArr[j]) {
        const smallNum = numToArr[i];
        numToArr[i] = numToArr[j];
        numToArr[j] = smallNum;
      }
    }
  }

  const new1 = numToArr[0] + numToArr[2];
  const new2 = numToArr[1] + numToArr[3];

  return Number(new1) + Number(new2);
};
