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

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

Output

You can vectorize the `update` function using NumPy's array operations to eliminate the explicit for loop. Here's how you can do that:

import numpy as np

def update(high, highest_number, delta):
    # Create a mask for all indices except the highest_number
    mask = np.arange(len(high)) != highest_number
    # Update the values using broadcasting
    high[mask] = np.minimum(high[mask], high[highest_number] + delta[highest_number] - delta[mask])
    return high
### Explanation: 1. **Mask Creation**: We create a boolean mask that identifies all indices in `high` except for `highest_number`. 2. **Broadcasting**: We then use NumPy's broadcasting feature to apply the operation to all relevant elements in one go. The `np.minimum` function compares each element of `high` (where the mask is `True`) with the calculated value based on the `highest_number` and `delta`. This approach is more efficient than using a for loop, as it takes advantage of NumPy's optimized routines for array operations.

    # Update only the masked elements

    return high
### Explanation: 1. **Mask Creation**: We create a boolean mask that identifies all indices except `highest_number`. 2. **Vectorized Operation**: We compute the new values for the `high` array at the indices where the mask is `True`, using `np.minimum` to perform the element-wise minimum operation. 3. **Higher Efficiency**: This approach is generally more efficient than using a loop, especially for larger arrays, since it leverages the underlying optimized C and Fortran libraries used by NumPy. ### Usage: You can call this function in the same way as before, passing in your `high` array, the index of the highest number, and the `delta` array. The function will return the updated `high` array.

Output

To vectorize the update loop in the `update` function, we can use NumPy's array operations instead of the explicit for loop. This will allow us to perform the operation on the entire array at once, which is generally more efficient. Here’s how you can rewrite the `update` function using NumPy for vectorization:

    # Update the high values for those indices where the mask is True
    high[mask] = np.minimum(high[mask], threshold)
    
    return high
### Explanation 1. **Mask Creation**: We create a boolean mask that identifies all indices except for `highest_number`. This mask will be used to select which elements of `high` should be updated. 2. **Threshold Calculation**: We compute the threshold values for the indices that are not `highest_number`. This uses broadcasting to apply the operation across the relevant elements of `delta`. 3. **Vectorized Update**: We use `np.minimum` to update the `high` array for the masked indices in one go, without needing to loop through each element. This approach is much more efficient and takes full advantage of NumPy’s capabilities for handling array operations.

### Explanation: 1. **Extracting Values**: - We first get the value of `high` at the index `highest_number`. - We calculate the `delta_difference`, which is the value that each element should be compared against. 2. **Vectorized Update**: - We use `np.where` to apply a condition across the entire `high` array. - The condition checks if the index is not equal to `highest_number`. If true, it updates the corresponding value with the minimum of the current value and the computed `delta_difference`. If false, it retains the original value. 3. **Return the Result**: - Finally, we return the updated `high` array. This approach is efficient and takes full advantage of NumPy's capabilities to handle array operations in a vectorized manner.
