In the Instructions is written:

operation(2,8) -> 2

2/*2 = 4

4/*2 = 8

After we subtract 1 from 'a' it is the same case. So for me the result has to be 2

C++, when I check for invalidValues.

state > 0x7f : all valid values test are passed, invalid values fail;

state >= 0x7F : all invalid values test are passed, valid values fail;

Can someone who passed the test to expain, may be I miss something.

Ok, thanks for pointing the issues. This is my first tries to create a Kata :) . I will have it in mind for the next Katas.

I have same issue, C++
