Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.

[Haskell] The default test harness doesn't compile, even with something as simple as
filterLucky = id
.It might be helpful to split up the unit tests into different cases for each of add, sub, and so on, rather than having a single "Should work for some tests" test case.
I think it should be made explicit that strings of different length should be truncated to the right, i.e. that they should match character-by-character from the left.
I'd make it clear that the "pyramid" is two-dimensional. It might also be a good idea to relabel the diagrams kg instead of кг.

[C++] If the input is a string, then it should be a std::string, not a char*.
The question should be more explicit what values are used. "char-Value" and "letter-Value" are ambiguous. Maybe try "ASCII character code"?
Probably strings with already capitalized vowels should also be checked in the test cases.
Some mention should be made as to what order the two sequences should be returned in, or their order should be considered unimportant.
