let largest = -Infinity; // Initialize largest to a very small value
let secondLargest = -Infinity; // Initialize secondLargest to a very small value

for (let i = 0; i < numbers.length; i++) {
  if (numbers[i] > largest) {
    // If current number is greater than largest, update both largest and secondLargest
    secondLargest = largest;
    largest = numbers[i];
  } else if (numbers[i] > secondLargest && numbers[i] < largest) {
    // If current number is greater than secondLargest but smaller than largest, update secondLargest only
    secondLargest = numbers[i];
  }
}

if (numbers.length >= 2) {
  console.log(secondLargest);
} else {
