Write a function to determine if a number is divisible by 21.
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.
my answer is correct,,,,,
my answer is correct.....
