##### Short Problem Definition:

Compute number of distinct absolute values of sorted array elements.

##### Link

##### Complexity:

expected worst-case time complexity is `O(N)`

expected worst-case space complexity is `O(N)`

##### Execution:

Additional storage is allowed. Therefore a simple python solution will suffice.

##### Solution:

```
def solution(A):
return len(set([abs(x) for x in A]))
```
