MAX & MIN, Second Largest

let arr = [8, 3, 2, 5, 4, 7, 6, 1] var maxValue = arr[0] var minValue = arr[0] var secondLargest: Int? for value in arr[1...] { if value > maxValue { secondLargest = maxValue maxValue = value } else if value > secondLargest ?? 0 { secondLargest = value } else if value < minValue { minValue = value } } // Output: MaxValue 8 // Output: SecondLargest 7 // Output: MinValue 1
