Last test case is wrong. Does not catch 500^3 == 1160^2 + 11120^2 and 500^3 == 2000^2 + 11000^2 .
First case is also wrong: 1^3 = 1^2 + 0^2. The problem doesn't specify positive numbers, so it is a valid solution. (If you *really* want to open a can of worms, a and b don't have to be integers, or even real numbers according to the test suite!)
You are right James. I have add some sentences to problem definition.
How on earth the leading solution size is 7? can you please provide it also for us ?
Test 12: There are two solutions missing [1160 11120; 2000 11000].
Thanks T. Dunker, I have corrected the mistake
