let smallestNum = array[0];
let secondSmallestNum = 0;
for (let i = 1; i < array.length; i++) {
  if (array[i] < smallestNum) {
    secondSmallestNum = smallestNum;
    smallestNum = array[i];
  } else if (array[i] !== smallestNum && array[i] < secondSmallestNum) {
    secondSmallestNum = array[i];
  }
}
