1) What does the following Python program do?

2) How would you rewrite this program using numpy?

m1 = [[12,7,3],[4 ,5,6],[7 ,8,9]]

m2 = [[5,8,1],[6,7,3],[4,5,9]]

rows = len(m1)

cols = len(m2[0])

#print("rows = " + str(rows) + " cols = " + str(cols))

res = [[0 for x in range(rows)] for y in range(cols)]

for i in range(len(m1)):

for j in range(len(m2[0])):

for k in range(len(m2)):

res[i][j] += m1[i][k] * m2[k][j]

for r in res:

print(r)
