🐄 MEUH Encoding

A fun Java project that encodes and decodes text using a custom binary-based system inspired by the cow “MEUH”.

Each letter of your input text is converted into binary (8 bits). Then, each bit is represented by the letters M, E, U, H — uppercase for 1 and lowercase for 0.

In other words, every byte becomes a pair of MEUH sequences, one for the first 4 bits, and another for the last 4 bits.

Example

For the letter a:

'a' → ASCII 97 → binary 01100001

Encoding rule: 0 → lowercase, 1 → uppercase

Mapping over M E U H M E U H:

01100001 → mEUh meuH

Result:

mEUh meuH

Decoding reverses the process: Uppercase becomes 1, lowercase becomes 0, and every 8 bits are converted back to the original character.

Encoding Example

select a function : 1

How It Works

1. Encoding

   • Each character → 8-bit binary

   • Each bit → M/E/U/H

     • Uppercase = 1
     • Lowercase = 0

   • Groups of 4 bits separated by spaces for readability.

2. Decoding

   • Ignores spaces.
   • Reads groups of 8 letters.
   • Converts uppercase/lowercase back into binary.
   • Translates binary → original character.

Example Session

Input  : test
Binary : 01110100 01100101 01110011 01110100
Output : mEUH mEuh mEUh mEuH mEUH meUH mEUH mEuh

Decoding it back gives you:
