Vectorize this update loop. Call the function `update`: import numpy as np def update(high, highest_number, delta): for i in range(len(high)): if i != highest_number: high[i] = min(high[i], high[highest_number] + delta[highest_number] - delta[i]) return high

Here's the vectorized version of the `update` function using NumPy:

I extracted the following code from that output:

Below is a student's answer to a question about how to vectorize this loop: def update(high, highest_number, delta): for i in range(len(high)): if i != highest_number: high[i] = min(high[i], high[highest_number] + delta[highest_number] - delta[i]) return high Here is their code: import numpy as np def update(high, highest_number, delta): mask = np.arange(len(high)) != highest_number high[mask] = np.minimum(high[mask], high[highest_number] + delta[highest_number] - delta[mask]) return high Did the student try to vectorize the loop? Don't tell me if they are correct or not. (I have tests for that separately which will catch any bugs.) Just tell me if they tried to vectorize the loop. End your answer with either the string "The student passes" if they tried to do a vectorized loop, or "The student fails" if they just wrote a for loop again.
Yes, the student did attempt to vectorize the loop in their code. They used NumPy arrays and vectorized operations such as boolean indexing with `mask`, element-wise comparison with `np.minimum()`, and broadcasting with `delta[highest_number] - delta[mask]` to avoid explicitly iterating over the elements of `high`.

The student passes The student did attempt to vectorize the loop using NumPy operations. They replaced the loop with a mask to select elements based on a condition and performed the calculations using NumPy's vectorized operations, such as np.minimum().
