took so much time, but very great kata. tbh I think it should be like kata 5, maybe less.

Print out the 5x5 example on a piece of paper, and then cut it a few times with scissors, then try to re-arrange it in a simpler configuration.

Maybe It could be 6 kyu.
But it is one of the best of 7 kyu's

And others are easier. Kyus of approved katas won't be changed, so it's pointless to post suggestions to do it.

I passed basic test but my solution is not valid with random tests. So guys would you like to share more longer test cases in order to see where I am miscoding somethings ?

This solution is awesome
But this kata feels like more than 6 kyu in some way
Anyway next kata !!!
Thanks to Sensei of this kata

It took some time, but eventually I completed this less solved kata among other kata's.
Great exercise.

Need to find out another way to solve the kata

Why is it awful? It's actual requirement, to make your solution pass the tests for inputs larger than 1000 (or whatever the range is). If you cannot pass tests and get timeouts, it means your solution is not efficient enough and you have not solved the kata.

It's not a kata issue. You need to find better solution.

I have passed first 4 tests but final test took so much time more than 12000ms
so I removed the final test. But when I decided to attempt , server time more 12000ms again
So I have solved the kata but server time is out
I think number must be under 1000 so we can pass
Generating so many numbers and checking them on a condition like this on this server is awful
