Problem 2. Sum and maximum

Description

Class Exercise 1

Write a program that reads an unknown number of integers from input until 0 is entered. Print the sum and the maximum of these integers.

Input format

Several lines, the $i$-th of which is an integer $s_i$. The last line is 0.

• For 100% cases, $|s_i|\leq 100$.
• All the integers before the last line are nonzero.

Output format

Two lines:

sum: xxx
maximum: yyy

where xxx and yyy are replaced with the sum and the maximum of the input integers. Note that the terminating 0 is not counted.

Examples

Example 1

Input:

1
2
3
0

Output:

sum: 6
maximum: 3

Example 2

Input:

-1
-2
-3
0

Output:

sum: -6
maximum: -1

Notes

This problem should be solved without arrays or dynamic memory allocation. Keep your solution simple.
