OMG, thank you so much for this. I kept seeing this syntax in katas and had no idea what was going on. Appreciate it so much!

That's great, nothing will explain it better, you need a promotion

That's impressive!

I can't believe you did this O.o

wow, great 💡 !!!

yes. The above comment.

Your IDE does not have the random code generator the testing suite here has. Each time you run your code, you pass some of the tests, then the testing halts. This is why you see a different number of passed tests. Typically, kata have 100 random tests. EDIT: this one has 200 random tests (in Python).

Hi,
So my code keeps changing the amounts of passed and fails everytime I click on attempt, without changing the code.
is it normal?

I'm coding in python 3, I tested in my IDE and works fine

oh ok, thanks for letting me know.

Everyone voted for 6 kyu, but i guess the moderators decided it was a 7kyu.

actually no, most people voted 7. The average you see on the "details" page of the kata is actually a floored value. Being the author, you cannot see it, but when I approved the kata, the other average was actually 7 kyu (which is totally appropriate for this task). Meaning, the average was somewhere between 6.5 and 7, floored to 6 in the details page of the kata.

Cheers

This is not 5 kyu or 6 kyu, because the task is very simple and can be bypassed by hardcoding all values (good "intentions" of using matrices are just intensions, the author has to compose the task in such a manner, that cheesing is worthless or is disabled by test suite).

Katas in 6 kyu are more difficult (maybe not by large margin, but still). Also, take a note, that current beta-process is more harsh that it used to be, with less katas are getting overranked.

yes, it should have. Everyone voted for 6 kyu, but i guess the moderators decided it was a 7kyu.
