When I calculate `int i = -1 % 2`  I get `-1` in Java. In Python, I  get `1` as the result of `-1 % 2`.
What do I have to do to get the same behavior in Java with the modulo function?

Mod in Java produces negative numbers

I came across an intriguing C code that prints `A + B`, but I have trouble understanding it.

## Input Format:

    A B

where `A`, `B` are integers between `0` and `10` separated by a single space.

## Code:

    main( n )
    {
        gets( &amp;n );
        printf(&quot;%d&quot;, n % 85 - 43);
    }
    
This was intended for short coding, please don&#39;t mind the warnings.

## What I understand so far:

`gets( &amp;n )` stores the ASCII values of A, space, and B in the lower three bytes of `n`. For example, `A = 3` and `B = 8` would yield `n = 0x00382033`. Given conditions prevent `n` from overflowing. But I do not understand how `n % 85 - 43` yields `A + B`.

How do you come up with these numbers?
