this is what i thought but couldnt manage to write :(

@mauro-1 is right that it won't traverse the entire array multiple times, but that's not the point. The worst case traverses almost the entire array three times: something like [1, 1, 1, 1, 1] * n + [0, 2] needs 3n + 3 comparisons (if my maths is correct) when n - 1 are sufficient.

Hi are you accepting translations? If so I might do a Go one.

There's always one.

The language specification needs quite a bit of work:

• The format for register names is not specified. It is assumed that they are single characters per the previous kata's description, but it should be reiterated here (and tested for).
• The description of labels needs a proper specification for what classifies as a label identifier. Also, for Haskell at least, there are no tests for programs that use a reserved instruction name as a label.
• For the "msg" instruction, it should probably be explicitly mentioned that string literals do not contain escape sequences (if that's the intention).

As you adviced, it worked after changing to PHP 8.0.
Thanks!

It looks like you might be on php 7.0, try changing the php version at the top of the page to 8.0. I'm not sure what causes this, but it might be a bug in the 7.0 runner, or the test suite isn't compatible with 7.0 anymore. Either way, changing it to 8.0 should fix it for you.

When I tried to submit in PHP, I encountered the following error.

Parse error: syntax error, unexpected '<', expecting end of file in /home/codewarrior/run.php on line 40

Since my program works fine in tests, I suspect it's a problem with the Kata.

Looks ok, approved

Lua translation!

Scala 3 update required

Scala:

• Tests emit warnings

Great kata! Also the first 2 kyu that I completed.

What is the point of getReg in C++ solution setup if it's not even tested?

Your code is not correct, it does not handle nested call correctly.
