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: [[-28, -44, 44, -19, 20], [-4, -1], [-44, 35], [-29, 5, -50, 40, -32], [11, -43, 23, -13], [12, -39, 7], [-44, -30], [21, 47, 29, -21, 39], [12, -34, 49, -40], [13, -44, -3, -45], [1, -45], [5, -26, -31], [42, -14, 17, 43, 33], [13, 23, -17, 49, -15]]
