Lua translation!

done

the input is an array of bits, so int would waste memory. bool would have been a better fit for this precise kata, yes, but unsigned char is the standard datatype for working with binary data (because it is byte-sized and because it avoids the usual caveats of bitwise operators with signed numbers)

Merged

Java: random tests are susceptible to input mutation

fixed here along with better assertion messages and an upgrade to JUnit 5

OP was mutating the input array and returning it; raising a more precise issue

the .upper() function makes the string all capitals, so we are just comparing wether the all capitals version of the string is equal to the string, therefore checking if the string is all capitals

did the same, so neat!

Oh, indeed, input is string, not list :)

who can explain me this

The sympy module is not among the external packages available on Codewars, you'll need to simplify the equalities manually, closing

no evidence given, closing

That's very clever, congrats!
