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: [[12, 41, 23], [18, -29, -9, -20], [-5, 24, -1, 26, 18], [-15, 18, 15, 13, -9], [23, 4, 31], [-10, -50], [30, -34, 3, 14, -5], [-33, -35, -22], [29, -18, -21], [-5, -36, -11, 0, -1], [-23, -31, 43, -35, -41], [37, -8, 16], [46, 15, 20, -31, -44], [-46, -48, -24]]

Solution: [12, -360, 11232, 18, 4, 500, -14280, -22, -18, 0, 0, -128, -40480, -52992]
