Given a string as input, move all of its vowels to the end of the string, in the same order as they were before.
Vowels are (in this kata): `a, e, i, o, u`
Note: all provided input strings are lowercase.
## Examples
```python
"day"    ==>  "dya"
"apple"  ==>  "pplae"
```
def move_vowels(input): 
    return ''.join(c for c in input if c not in 'aeiou')+''.join(c for c in input if c in 'aeiou')
def move_vowels(input): 
    return ''.join(c for c in input if c not in 'aeiou')+''.join(c for c in input if c in 'aeiou')
