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: [[39, -16], [32, 14, -12, -33], [15, -10], [35, 21, 16, -16, -33], [-25, -23, -29, 20, 50], [10, -36, 40, 8, -30], [49, 45], [21, 8, -21, 32], [-7, 11, -20, -27, 5], [42, -12, -8, -46, 32]]
