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: [[-9, -26], [-26, 23, -3, -25, 5], [-28, -15], [45, -6, 12, 49, 45], [31, 22, -11], [41, -34, 18, -7, 31], [43, 23, -49, -34], [27, 0, -39, -40, 27], [-27, -4, -3, -32, -35], [-32, 11, 24, 11, -35], [42, -10, -43, -37], [-43, -2], [-28, -38, -17, 34, 19], [-46, -10]]
Student:
[-26, -26, -28, -72, 22, -612, -34, 0, 128, -768, -420, -2, 36176, 460]
