The test suite was broken, as many of you suspected. I fixed it and rescored the problems.
I like this problem:)
very interesting problem
Good
The test case 3 is totally wrong. It needs immediate correction. The code maker didn't notice that b=25 is a number not a single digit. If you're doing the sum of digits it always ends up with a single digit, it will never end up with number cause number itself is carrying multiple digits.
Just for the badge ; )
