Instructions: 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.
Input: [[2, -15, -6, -43, 16], [-21, 3], [31, -48, 42], [-35, -49], [-6, -6, 48, 39, 33], [-34, -3], [21, -10, 4, -1, 40], [15, 4], [-26, -46, -26], [13, -43, -8, 27], [46, 21, 36, -14, -49], [-19, 3], [-48, 1], [5, 31, -22, -28], [-4, 27, 49, -47, -33]]
Output:
[-192, 0, -2016, 0, 1728, -34, -1600, 4, -31096, -8, -23184, 0, -48, 616, -4]
