import numpy as np

x = np.array([[1,2,3,4,5], [6,7,8, 9, 10], [11,12, 13, 14, 15], [16,17, 18, 19, 20] ])

1. Show how to convert the array to floating point numbers.

2. Show how to assign all the elements that are even (index 0, 2, 4, ) to 0 and then assign all the odd (index 1, 3, 5, ) elements to 1.
