Given an integer number, $n$, create an $n$ by $n$ array that is filled with with alternating O's and 1's Use the built-in NumPy methods to solve this problem. No for loops, please. Have fun with it! You can solve this in three lines. In [264]: import numpy as np import math def np4 (n): a np.zeros(n*n, dtype-int) a[::21-1 return a.reshape (n, n) raise NotImplementedError() Expected output np4(4) Use the cell below to test your function. cessing math: 100% 4(3)
