             Summary: [C++] Create a compute function returning indices of non-zero values
                 Key: ARROW-13035
                 URL: https://issues.apache.org/jira/browse/ARROW-13035
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Antoine Pitrou


This would be similar to Numpy's {{nonzero}} function:
[https://numpy.org/doc/stable/reference/generated/numpy.nonzero.html]

{code:python}
>>> arr = np.array([4,5,0,6,0,5])
>>> np.nonzero(arr)
(array([0, 1, 3, 5]),)
{code}
