WebbThis will give us a 1D array of shape (2,) with values [1, 2]. Finally, we use boolean indexing with input.any(axis=1) to only select elements from the index array where there is at least one True value in the corresponding row of the input array. This gives us the desired output array of shape (2,) with values [1, 2].
