  • ## Credit
  • This challenge is taken with permission from https://www.mysterytwisterc3.org/en/challenges/level-1/beaver-code
  • ## Description
  • The encryption method is as follows:
  • The plaintext is divided into two halves, odd positions and even positions.
  • Example: `'CRYPTO' -> ['CYT','RPO']`
  • This is then applied recursively to both halves, until each part is two letters or less. The parts are then merged.
  • `'CRYPTO' -> ['CYT','RPO'] -> [['CT','Y'], ['RO','P']] -> 'CTYROP'`
  • ## Challenge
  • Given a string encrypted with this method, **decrypt** it.
  • Valid input formats: ['CTYROP'], 'CTYROP'
  • ## Test cases
  • ```
  • CTYROP -> CRYPTO
  • EOYCTNNPRI -> ENCRYPTION
  • RUOENFSEAFMRDHT -> RANDOMSTUFFHERE
  • ```

  • Note: the **encryption** of the last test case is the same as the **decryption**, make sure you're **decrypting**!

Beaver Code Decryption
## Credit

This challenge is taken with permission from https://www.mysterytwisterc3.org/en/challenges/level-1/beaver-code

## Description

The plaintext is divided into two halves, odd positions and even positions.

Example: `'CRYPTO' -> ['CYT','RPO']`

This is then applied recursively to both halves, until each part is two letters or less. The parts are then merged.

`'CRYPTO' -> ['CYT','RPO'] -> [['CT','Y'], ['RO','P']] -> 'CTYROP'`

## Challenge

Given a string encrypted with this method, decrypt it.

## Test cases

```
CTYROP -> CRYPTO
EOYCTNNPRI -> ENCRYPTION
RUOENFSEAFMRDHT -> RANDOMSTUFFHERE
```
