for a scoring system in a game, a player can score on 12 different subjects. For each of these subjects, a score is kept (normally in the range of -5,5). What I want from an array is the index of the two highest and lowest scoring subjects.

scorep1[0] - scorep1[11] can have the same score. I've tried doing it via the max() command, or the sort() command, but when there are two identical entries, it messes it's up.

I'm not necessarily interested in the score, I just want the indices (the subjects) to display what subject is best and what is worst for a student.

Any help on this?

for a project we are trying to convert a old fashioned pick-nick table into an interactive one. The last step is tracking handmotion. What I need to detect is gesture swiping left or swiping right, that's all. Colour tracking is not really the option because the colour of the wood is detected as skin colour. Can openCV help here, or  http://code.google.com/p/ehci/ ?

Anyway, I'm not experienced enough to program it myself, but if someone can give me a setup I might get there (and learn from it!).

Thanks in advance!
