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: [[-30, 43, 15, 49], [33, -48, 17, -13], [47, -44], [22, -40, 41, -38, 34], [-13, -5, -30], [21, 26, -22]]
Solution:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
