Each lowercase letter is stored as 2 bytes, and the remaining characters are 1 byte. If I were to ...

Simple Task Solved Thrice
You should write 3 programs and/or functions in one language.
All of these programs should solve the same task but they all should give different (but valid) outputs. (I.e. for every pair of programs their should be some input which generates different (but valid) sets...
