I'm not going to use n-uplet, dynamic array of array of Byte is enough.
Though not very optimizing, I can use 2 step process:
1. Generate all lists (array of Byte) of length N which each element ranges
from 0 to C.
2. Filter which has sum=C.

Don't worry, I'm not gonna use it because it has to be done in procedural
way (I haven't taken Functional Programming class yet). The reason why I ask
is I'm HOPING that if I can understand how it works, implementing the
procedural form would be easy. I've read somewhere that functional language
can be implemented in procedural one. In fact, GHC outputs C code.
Thanks for the answer. I'll use it to learn, it's quite difficult to switch
from procedural to functional. I mean, in procedural it's easy to find the
fastest solution using brute force. This can't be done in functional.
