Pure fun :)

Hello,
Can anyone can tell me what format response should be in C?

Thats brilliant man!

Way more challenging than rest of 6 kyu katas - not sure it's possible to change it now but at least few of 4 Kyu katas were less demanding.

In my opinion it would be much better kata if size of table would be different for each test

Thanks, it feels like I play tic tac toe and meanwhile you playing 5D underwater chess :D

Tests are ok, just description can be missleading.
In my opinion it would be much easier to read in form like:

Priority order:

1. Number of appearances (values 1 should be excluded)
2. '1','2' or '='
3. Ascending lexicographic order

Hello, can you explain me why this actual work?

There is a minor issue with this kata:
In description there is information that angle in return array should be rounded,
logical approach is to round values for angle too but they should be floored instead.

Cool kata.
Same occurs for C - took me some time before I realized source of not correct values.
Would be cool to add odd numbers of a and b to basic tests for next who will be trying to pass this kata.

@rowcased
You have right - after isolating test it turned that all is OK for this case.
I didn't expected that I can get response from another case just after data from case I was trying to figure out.
Thank You.

Sorry but I dont understand why it is not issue:
In instruction you have even examples,one of them is:

• add_letters(2, {'z', 'a'}) == 'a'
  So if test have two values 'z' and 'a' as input thats mean output should be 'a' not 'z'.
