This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information.If this question can be reworded to fit the rules in the help center, please edit the question.

    
definition of distinct –  Matt Эллен Mar 27 '12 at 14:47
    
I've voted to close as General Reference, but I will point out that it's more often the number of discrete values, or in less elevated contexts, the number of different values. To my mind, distinct here is a bad choice, being neither the "academic/formal" nor the "popular vernacular" version. –  FumbleFingers Mar 27 '12 at 16:16

This is more a programming question than an English question so I suspect it will soon be closed, but for what it's worth:

As Andrew and Will note, "distinct" means "different". So the problem is saying that you are to find the set of values -- I presume where you get the "raw" set is explained earlier in the problem -- and then take each value mod 42 (i.e. the remainder when you divide by 42), and output a list of only the distinct values found, i.e. if the same number shows up more than once, only output it once.

Dictionary reference

Separate; different.

In the specific example, you discard duplicated numbers. The number of distinct values in the set {1,1,2,2,3,4,56} is five: {1,2,3,4,56}
