Ruby String Translation

Question

I want to find the successor of each element in my encoded string. For example K->M A->C etc.

string.each_char do |ch| 
    dummy_string<< ch.succ.succ
end

However this method translates y->aa.

Is there a method in Ruby that is like maketrans() in Python?

Answer 1

You seem to be looking for String#tr. Use like this: some_string.tr('a-zA-Z', 'c-zabC-ZAB')
