You wrote the answer in the question. 6=1, 12=2, 18=3 ... Try to figure out the logic of these equations

Oh. Finally understand the logic of flat rows.
Just did it. Odd n`s are foooo

All examples my code does perfectly, but test cases if very "bad".
When n is odd - heart is very asimetric, and strange.
Rows of ■■■■■■ in test cases is placed not by the same logic, as in examples

Cant catch the logic in one moment: how many ■■■■■■ rows should I draw? Sometimes its (n/2) // 2, but sometimes - not

Easy kata. 7 kyi

Героям Слава!

Some test cases will give you an error. You have to find out how to round days

It was hard to understand the logic of the description, but very easy to write the code.
7 kyu.

If you don`t have much practise in codes with date and time - this kata is for you.
Thank you for helping me in my study

It was very ... non-standard. Thank you. I literraly heard how my brain worked.

This kata requires mathematic, not programing

Thank you. Great kata!

Logic of counting time is false. Total waiting time has to be the last customers waiting time, but not the sum of all. Because waiting time of previous customers is already counted in the last customers waiting time/
So, [4, 3, 2] has to be 13 (4+2 + 3+2 + 2), but not ((4) + (4+2 +3) + (4+2 + 3+2 + 2))

One of the most interesting kata I've ever solved. Thank you

It seems to me, that this kata is little bit harder than 7 kui.
