HW2, all test passed on my pc but 3 failed when I upload the file

Question

I've just uploaded my solution to  the homework. When I tested it on my pc it gives 16/16 test passed but when uploaded only 13 out of 16 test are completed successfully.

Don't know what else to do.

Here are 2 screenshot of the problem.

If you go to the correctness tab you should see why those 3 tests failed. With only the screenshots you gave us we can't do much.

Uh, ty, I think I got the point. The test failed were the long ones and they were failed due to exceeding the 6s timer.

I'll leave the post here in case anyone will have my same problem

I'm glad that you found the error! Hopefully you find a way to solve it too!

I had the same problem, thank you for sharing, I just resubmitted the program optimizing the code, but I'm not sure it'll be fast enough, any suggestions for the optimization?

The optimisation really depends on your code, so I can't suggest you a lot of things, except maybe the most obvious one: reduce the amount of loops in your code (if you even have any).

I'm sorry I can't do more...

Thank you for the tip, at the end I just created some variables at the beginning of the program and used those to shorten the code:)
