The test cases are wrong. It shows an expected output with numbers that aren't in the original matrix, besides i had to click on the attempt button several times without changing the code until it finally marked my solution as correct.

You've made me laugh!!! ;)

I did not chose "rank up" but "foundations"
I thought rank up was more if you were experienced andd
quickly wanted to get to a level more appropiate for
your experience.
I thought foundations was the usual route for just
progressing normally as you obtain more experience.
I guess I need to reread how this site works :)

I assume you mean when selection 'Rank up', right?
It depends a bit on how many katas are actually available in the chosen language.

As a 5 kyu why am I getting 7 & 8 kyu kayas to solve.
I thought at each level you get that level kayas

OP solved it, closing

Allright thanks, im new so i didnt know you cant edit the given part of the challenge.Also ive never seen that so i was a bit confused.

I did this challenge in C and works in all computers and online compilers that I was tried except hte integrated in the challenge, it yields an invalid memory access error, but only here happens. I don't know why...
