Better figuring out looking at the examples although I think the description is clear and simple enough to understand as well.

Fixed. Thanks

Almost there. First, you wrote Enhancment in the section title and another paragraph, missing an 'e': "Enhancement". But I would also change every mention of "second" to "other", e.g. here:

Now there are 2 'Axe of fire', so let’s enhance one of them by destroying the second other one.

(Because "second" implies ordering, i.e. we destroy the one we found last. That isn't the case though.)

Thank you. I agree this kata is more like 4kyu. But since I am new to creating kata, I acted stupidly and was the first to post the Ruby version, and almost everything is easier in Ruby, especially metaprogramming, so those who evaluated it after solving it in Ruby and rated it easier. Well, besides this, new kata are assessed differently than the old ones, so new ones on the same kyu will often be more difficult, I don’t know exactly why this is so.

Thanks for the help. Corrected it, is it clearer now? Unfortunately my English is not very good yet

Either I underestimated this kata going in, or this kata was on the more difficult end for 5 kyus. Either way, this was a pretty good kata and I enjoyed the challenge.

Thank you! That fixed the problem.

apologies for the late response, but it should be fixed and working properly.

Would this be possible for someone with edit permissions to fix this bug?

Read several times before understood what was going on. Probably better to emphasize that first the queue is sorted by priorities, then with every "known customer" swapping occurs.

The following compile errors were encountered while attempting to pass:

error[E0308]: mismatched types
  --> src/lib.rs:98:32
   |
98 |         assert_eq!(get_in_line(&[1,1,3,2,0]), 3);
   |                    ----------- ^^^^^^^^^^^^ expected struct `Vec`, found array `[{integer}; 5]`
   |                    |
   |                    arguments to this function are incorrect
   |
   = note: expected reference `&Vec<i32>`
              found reference `&[{integer}; 5]`

Could you please fix &[1,1,3,2,0] with &vec![1,1,3,2,0]? Other tests likewise.

Also the function does not require a mutable reference, probably you want to remove "mut " from calls as well: assert_eq!(get_in_line(&mut vec![1,1,3,2,0]), 3); -> assert_eq!(get_in_line(&vec![1,1,3,2,0]), 3);.

That is true, i hadn't had much experience with Rust when making this problem and i was running into issues just passing in Vec<i32>. Now I've looked back at it and realized it's an easy change.

suffering for what...

mine better!!!!!!!!!! (thanks to sensei)

Better to read the condition carefully first...
