In input string ```word```(1 word):
* replace the vowel with the nearest left consonant.
* replace the consonant with the nearest right vowel.

P.S. To complete this task imagine the alphabet is a circle (connect the first and last element of the array in the mind). For example, 'a' replace with 'z', 'y' with 'a', etc.(see below)

For example:
```
'codewars' => 'enedazuu'
'cat' => 'ezu'
'abcdtuvwxyz' => 'zeeeutaaaaa'
```

It is preloaded: 

```
const alphabet = ['a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z']
const consonants = ['b','c','d','f','g','h','j','k','l','m','n','p','q','r','s','t','v','w','x','y','z'];
const vowels = ['a','e','i','o','u'];
```

P.S. You work with lowercase letters only.
