NumPy - Indexing and Slicing

What will be the output of this code?

import numpy as np
arr = np.array([[1, 2], [3, 4], [5, 6]])
rows = [0, 2]
cols = [1, 0]
print(arr[rows, cols])

A[1 6]

B[2 6]

C[2 5]

D[3 5]

Step-by-Step Solution

Solution:

Step 1: Understand the array and indices
arr is a 3x2 array. rows = [0, 2], cols = [1, 0].
Step 2: Select elements at (0,1) and (2,0)
arr[0,1] = 2 and arr[2,0] = 5, so output is [2 5].
Final Answer:
[2 5] -> Option C
Quick Check:
arr[[0,2],[1,0]] = [2 5] [OK]

Quick Trick: Pair row and column indices to select elements [OK]
