Note: The index starts from in lists.
`l1` is a non-empty list of integers. What is the output of the following snippet of code?
```
# Hint: str(3) is '3'
l2 = []
for i in range(len(l1)):
condition_1 = not (i % 2 == 0)
condition_2 = not (len(str(l1[i])) != 3)
if condition_1 and condition_2:
l2.append(l1[i])
print(len(l2))
```
