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: [[-42, -27, -46, -45], [45, -32], [-44, -8], [-23, 2], [15, 2, 17, 7], [27, 39, -38, -39, -9], [2, 46, 42, -33], [-47, 33, -50], [-9, -25, 8, 23, -1], [-46, -20, 27, 47, -10], [-13, 9, 22, 29, -40], [-45, -5, -30], [36, -20, -42], [-33, 39, -28, 20]]
