module ReverseString
def self.reverse(input : String) : String
input.reverse
end
end
This is the simplest and most exemplary solution, using the built-in String#reverse method.
Internally, it uses a very optimized implementation, using a buffer and working directly on the string's bytes.
If curious, check the source code.
