Hm, not "substring" as in String at least, but that solution does
give the following results:
Prelude List> sub "ell" "hello"
Prelude List> sub [3..5] [1..10]
Prelude List> sub [2,4] [1..5]
Prelude List> sub [2..6] [1..5]
Do you mean "subset" with "subsequence"?
Nobody can be exactly like me. Even I have trouble doing it.
