Explanation of sentence [closed]

Question

I don't understand this sentence.... I know the meaning of all words except distinct... I looked in dictionary.. but I don't understand..:/

Output the number of distinct values when considered MOD 42, one per line for each test case.

Answer 1

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.

Answer 2

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}
