Divisible by 21 or by 7 ?
What is the name of the function that you want ?
divisible_by_21.m or divisible_by_7.m (you test both)
Why do you forbid all these functions ?
A lot of why ...
The problem maker in this case (no pun intended) simply copied the test case from my Divisible by 7 problem and made some edits, but obviously not enough to make it solvable. I've greatly simplified the test suite for this problem so that it is now solvable.
Thanks Grant.
