Second Largest Number Python

PROGRAM TO PRINT THE SECOND LARGEST NUMBER

def print2largest(arr, arr_size):

  

    # There should be atleast

        # two elements 

    if (arr_size < 2):

      

        print(" Invalid Input ")

        return

      

  

    first = second = -2147483648

    for i in range(arr_size):

      

        # If current element is

                # smaller than first

        # then update both

                # first and second 

        if (arr[i] > first):

          

            second = first

            first = arr[i]

          

  

        # If arr[i] is in

                # between first and 

        # second then update second 

        elif (arr[i] > second and arr[i] != first):

            second = arr[i]

      

    if (second == -2147483648):

        print("There is no second largest element")

    else:

        print("The second largest element is", second)

arr = [12, 35, 1, 10, 34, 1]

n = len(arr)

  

print2largest(arr, n)

OUTPUT
