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.
Example: [[7, -3, -3, 11], [-6, -6, -5, 2], [-8, 4, -3]]
Example solution: [0, 72, -32]
Example 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.

Problem: [[-24, 37, 14, -36], [-23, 33, 13, 12, -44], [45, 17, -17, -23], [28, 29, -2, -34, -16], [-34, -27, 30, 0, 0], [19, 32, -4, -12, 27], [3, 20, 47, 14, -49], [-33, -48], [41, 40, 24, 32], [-4, 30, -37, 34], [38, 8], [34, 16, -39, 47, 40], [-29, 37, 31, -20], [-8, 14, -2], [21, 26]]

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.
