     public static int getTheSecondlargest(int[] arr) { 
        int max = Int32.MinValue, secondmax = Int32.MinValue;
   
        for (int i = 0; i < arr.Length; i++) {
            if (arr[i] > max) {
                secondmax = max;
                max = arr[i]; 
            } else if (arr[i] < max && arr[i] > secondmax) {
                secondmax = arr[i]; 
            }

        int[] arr2 = {1, 1, 2, 1, 1};
        Console.WriteLine(getTheSecondlargest(arr2));
         
        int[] arr3 = {5, 5, 5, 5, 5, 5, 5};
