The Karaca's Encryption Algorithm

Make a function that encrypts a given input with these steps:

Input: "apple"

Step 1: Reverse the input: "elppa"

Step 2: Replace all vowels using the following chart:

a => 0
e => 1
i => 2
o => 2
u => 3

// "1lpp0"

Step 3: Add "aca" to the end of the word: "1lpp0aca"

Output: "1lpp0aca"

Example

Encrypt("banana") ➞ "0n0n0baca"

Encrypt("karaca") ➞ "0c0r0kaca"

Encrypt("burak") ➞ "k0r3baca"

Encrypt("alpaca") ➞ "0c0pl0aca"

Notes

• All inputs are strings, no uppercases and all output must be strings.
