[Solved] Given two numpy arrays:a = np.array([[2, 4], [6, 8]]) b = np.array([[1, 3], [5, 7]])Which of the following computes the element-wise difference and then divides each element by 2 in a single line? | NumPy

NumPy - Array Operations

Given two numpy arrays:

a = np.array([[2, 4], [6, 8]])
b = np.array([[1, 3], [5, 7]])

Which of the following computes the element-wise difference and then divides each element by 2 in a single line?

A(a - b) / 2

Ba - (b / 2)

Ca / 2 - b

Da - b / 2

Step-by-Step Solution

Solution:

Step 1: Compute element-wise difference
Subtract b from a element-wise using a - b
Step 2: Divide each element by 2
Divide the resulting array by 2 using / 2
Step 3: Combine in one line
(a - b) / 2 performs both operations correctly
Final Answer:
(a - b) / 2 -> Option A
