Problem 54700. Leyland Primes
24^5+25^12 in test case 6 is greater than 2^53 and therefore cannot be tested using ordinary double precision numbers.
Tim, William, Chris -
The faulty test case has been edited out of the test suite. Apologies for the inconvenience. Please attempt/edit your answer accordingly.
Dyuman, it looks like Test 6 is still being applied.
I thought commenting it out would work, but it didn't. I have removed it completely and rescored the solutions, good to go.
Do rate the problem!
ismember() is not allowed now!
I expected that! But I really couldn't see why one would write a complicated program when there are just a handful of well-known values.
I have written a proper solution now, and it works on everything except Test 6. As Tim has pointed out, the argument in that case is larger than flintmax. isprime() evaluates to zero.
