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.
One example: [[7, -3, -3, 11], [-6, -6, -5, 2], [-8, 4, -3]]
Solution is here: [0, 72, -32]
Explanation: 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: [[8, 29, 2], [-21, 45], [-2, 7], [4, -10, -45, 33, 50], [36, 1], [46, -23], [45, -22, -14, 15]]
Solution:
[16, 0, -2, -2000, 36, 46, 308]
