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: [[-25, 42, 40, 41], [44, 22, 29], [21, 21], [-41, 7, 11, -46, -45], [50, -26], [43, -32], [42, 3, -20, 31], [-5, 12], [42, 20, 34, 50, 21], [19, -13, 24], [34, -17, 34, -6]]
Solution:
[1680, 968, 0, -46, -1300, -32, -840, 12, 1428000, 24, -6936]
