Second maximum Write a program that reads a sequence of integers until 0 and prints the second greatest value. For example, for the input 2 3 5 5 0, the program prints 3 because 5 is the greatest value and 3 is the second greatest value. If the second maximum does not exist, the program prints 'No second maximum. Example of input: 10 245 8 360 Corresponding output: 8 Example of input: 50 Corresponding output: No second maximum Example of input: 7 70 Corresponding output: No second maximum
