this one isn't 6 kyu no way a newbie is solving this on his own.

Good!

Thank you for your comment and advice. Next time I will come up with an original idea for my kata and provide more detailed information about the theme of my kata.

Regarding kata themes, you need to assume that your audience has no idea what you are talking about. Many people will have never even heard of military facing movements, let alone know what each command is. Any information important for your kata must be explained.

Regarding tests, I would strongly suggest going to another kata which you have solved, go to the discourse page and click 'view solutions'. You can have a look how proper tests are supposed to look, how to import solutions, etc. (Note, that older katas tests might not be good either, have a look at a couple different ones to be sure).

Finally, in case you haven't seen this yet, read this

I am sorry for my broken english, it is not my first language. It is mentioned though that the faces are not case-sensitive. This kata was inspiried by military facing movements, I had no idea that this is some kind of duplicate. I couldn't make complete random test cases because I don't know how to import my complete solution to compare the outputs. Thank you for your comment

• The description is written in broken English
• It is not explained what "front face" does
• My solution ignores "F" turns, as I assumed that they do nothing, but the author's solution changes direction to "F" - if that's the indended behavior, it should be properly tested
• It is not stated how to handle lowercase letters
• The "random" tests are not actually random
• Trivial map/filter/reduce is not a novel kata idea (I also vaguelly remember doing something similar in a different kata, although idk whether it was the whole task, or just a part of it, so this might be a duplicate too)

input: 'RL'
outcome: 'F' should equal 'B'

why?

wouldn't you turn right, then turn back left, and then immediately be facing front again?

It should also be mentioned that starting position is front ('F')

no actual description.

• What are the inputs?
• what is actually meaningful in them (that part is covered, but it's rather hard to see what are the data or not for now)
• outputs are never described

No random tests.

I came up with the same solution, thought I was doing some horrible hack xD

Writing a trivial comparator is a duplicate.

Нужно узнать сколько времени понадобится черепахе B догнать черепаху A, зная их скорости и насколько отстаёт черепаха B.

I had this too, so it's not something extraordinary. Solve other katas and come back to it later. Usually after some time you will be able to solve the kata if you keep learning or just unlock the solution and remember how to solve that specific problem.

nice kata
