Grant, your divisible series should become a challenge by its own right.
Thanks for the vote. We'll see if the Cody team agrees. I just added a few more problems to the series today to round it out.
Nice problem - deceptively tricky.
my solution is failing because when the numbers are very large it gets confused by the "eXX" where XX is the exponent associated with the test number.
Can i get help on how to avoid this?
You need to find a way to operate on the string, which may involve mathematical operations on small portions of the string, bit by bit, converting small portions of the string to a number, in an iterative fashion, etc., based on the method you choose. str2num() is subject to loss of precision for very large numbers and will not work for at least one test case in essentially all of these problems (by design).
