This is NOT a kata issue. When your solution can't pass the tests printf starts outputting text in an "unexpected" way. Maybe your code is working correctly in these cases, but it's still wrong.

When I ran the program it fails for "a" and "aa b". But when I checked the output in printf, values are "a" and "aa". Then why tests are failing.

1. You might be misinterpreting the logs.
2. printf may act funny from time to time making it even harder to understand what's happening.
3. C version is alright; your code must be the source of the issue.

But issue happen only when the answer is a like "aaa b", "aa b", "a". But it passed for "b aa".
@FArekkusu Can you elaborate why printf function act funny.
