grades = np.array([[87, 96, 70], [100, 87, 90], [94, 77, 90], [100, 81, 82]])
To select and return the second and fourth rows of the grades array,
replace ??? with:


In[1]: ??? ..... ANSWER ......grades [[1, 3]]


What is the output of the following:
In[1]: {1, 2, 4, 8, 16} & {1, 4, 16, 64, 256} ..... ANSWER ......{1, 4, 16}
