Ok, but this kumite uses python in tests and I'm too lazy to write a translation to C.

Division is a slow operation, it's a way to reduce its usage.

This function does a lot of unnecessary calculations including division. If you have to do one conversion - do exactly one instead of 2.

Added sample tests

Oh, I see

Already got it, but thank for answering

This one is like an advanced version of BFxor. I think there's no problem with this.

I don't know which test it is. I updated testing system, your code works and passes all the tests. Try to test it again - there're no random tests.

Done

Idk if it's a good decision to put link directly to the training page. Changed it anyway

Done

Added a test for the edge case when 2 numbers add up to 256.

Removed all ascii references from the description
