Return a new array consisting of elements which are multiple of their own index in input array (length > 1).
Some cases: 
```
[22, -6, 32, 82, 9, 25] =>  [-6, 32, 25]
[68, -1, 1, -7, 10, 10] => [-1, 10]
[-56,-85,72,-26,-14,76,-27,72,35,-21,-67,87,0,21,59,27,-92,68] => [-85, 72, 0, 68]
```
def multiple_of_index(arr):
    return [y for x,y in enumerate(arr[1:], start=1) if y % x == 0]
def multiple_of_index(arr):
    return [y for x,y in enumerate(arr[1:], start=1) if y % x == 0]
