Teacher: In this task you will be given a list, of lists, of integers. For every inner list contained in the input list, you should multiply every even number in that list. The output should be a list of integers with the same length as the number of lists in the input list. If there are no even numbers in an inner list you should output 0 for that list.
Teacher: Now, understand the problem? If you are still confused, see the following example:
[[7, -3, -3, 11], [-6, -6, -5, 2], [-8, 4, -3]]
Solution: [0, 72, -32]
Reason: The first inner list has no even integers, so the first number in the output is 0. The second list has -6, -6, 2 for even integers so the second output is 72. The third list has -8, 4 as even numbers so the third output is -32. This is a good example.

Now, solve this instance: [[48, -43], [-25, -49], [29, -12], [26, 38, -18, -27], [7, 2, -30, 15], [-5, -24], [-12, 10, 47, 46, 37], [-12, -42, -16, 5, -14], [5, 31, 2, -27], [-44, -5], [32, 23, 16], [45, 18, -8, -39], [-37, 14, 31], [-39, -31], [-9, 9, 10]]
Student:
[48, 0, -12, -17784, -60, -24, -5520, 112896, 2, -44, 512, -144, 14, 0, 10]
