You can just use var keyword for java 11, without needing to import Annotation

Just treat input as string and not a number.

Harder than i thought... in Javascript with time constraints.
But interesting to solve.
In java it's much easier with timeout as it seems.

If we add some validation in js like code must contain minimum one of each ["$","{","}"] and two ` - tests will be more precise;

I think its nearer to 6 kyu, took me some more time than was expected.

I think 5 kyu is just the right level, you can check the older katas, there are some easier than that and 5 kyu must not be hard;

I tried my solution from here in leetcode and it was 2x faster than before)
so codewars helps with better practices.

Yes, kata is quite good

Yes, random tests use very large arrays

Great kata, never used XOR in 10 years of programming actually, so for me it took some time to get hold of it. I think 6 kyu would be better suited for this.

5 - 6 kyu is quite ok for this, if you look for older kata, they are easier. Its hyperinflation in difficulty ranking happening.

My favourite kata) i like to send it to experienced java developers and they are very suprised)
Also task briefing is amazing.

Great Kata! As its somewhat different from base ceasar cipher, good experience!

great kata! helps with understanding how property accessors work.
