Consider the following code:
def mystery(a):
for i in range(len(a)):
if (a[i]
print(a[i], end = " ")

# ********** MAIN **********
s = [63, 72, 21, 90, 64, 67, 34]
mystery(s)

What is the output?
1) Nothing is output, you cannot do modular division on strings
2) 63 21 64 34
3) 72 90 64 34
4) 63 21 67
