The second maximum

Explanation of the Code

1. Initialize Variables:
   largest = second_largest = float('-inf')

   • Initialize largest and second_largest to negative infinity (float('-inf')) to ensure any input number will be larger.
2. Reading Input and Finding the Largest and Second Largest Numbers:
   while True:


       num = int(input())


       if num == 0:


           break


       if num > largest:


           second_largest = largest


           largest = num


       elif num > second_largest:


           second_largest = num

   • Use a while True loop to continuously read input.
   • Convert the input to an integer using int().
   • If the integer is 0, break the loop.
   • If the integer is greater than largest, update second_largest to largest and update largest to this integer.
   • If the integer is greater than second_largest but not greater than largest, update second_largest to this integer.
3. Printing the Second Largest Number:
   print(second_largest)

   • Print the value of second_largest after exiting the loop.
