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.

Not a good idea to use "strlen()" in the loop invariant -- it needs to re-scan the string for the ending '\0' on every call...
Fixed.
no answer from OP and no evidence given
Doh! I missed that caveat -- my bad.
Something seems wrong with the first sample C++ test. The expected makes no sense.
Expected: equal to [ "HT", "HT", "HT", "HT" ]
Actual: [ "HH", "HT", "TH", "TT" ]
Update: I see now; the Expected and Actual are reversed in the test.
please read the description...
A C edge case test seem wrong. Having a zero numer (and non-zero demom) should yield '0' with a size of 1, not the empty set.

Friendship is commutative. (The description doesn't explicitly say this, but I think it's clear from the example given, which has
Harry/Ron
but notRon/Harry
.)Can you post the test case (the first few lines of it, at least) that produced the strange behaviour?
I can't pass the first test case. I had a solution that did return a clique (allowing for if X knows Y, then also Y knows X). The test said there shouldn't be any cliques. So then I coded up a non-commutative alogrithm, and then for the same problem the test harness says there should be at least one (!).
yes, you're right.
It's a better practice to make 'i' the same unsigned type as 'a'. As an int, 'i' could underflow for large values of 'a'.
