TASK DEFINITION: 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.
PROBLEM: [[-43, 34, 32, 4, 22], [-9, -20, -4, 24, 1], [-7, -16], [46, -47], [-50, 41], [16, 0, -49, 49, -23], [12, 13], [-46, -1, -24, 43], [39, -23, -13, -42, 44], [35, -45], [42, -7], [-34, 26, -13], [-20, -27, -16, -6]]

SOLUTION: [95744, 1920, -16, 46, -50, 0, 12, 1104, -1848, 0, 42, -884, -1920]
