Check your int-long castings

Thanks for clarifying my doubt

This kata is a draft, you cannot complete it.

After clicking "Attempt" -> It shows "You have passed all of the tests"
Yet I am not able to "Submit" the solution.
i.e, "Attempt" button is not changing to "Submit" button.

Can you please look into this issue and may be explain why is this happening ?

@Jo_kur: Your solution is far too complicated. See things simply.

I have the right algorithm for solving this kata, but after making the algorithm more efficient thrice, It still timed out. No idea.

Please don't spoil solutions.
