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.
Input: [[20, 19], [-48, 36, 37, -19], [23, -45, 8, 49], [43, 13], [9, -4, -39, -6, -1], [35, 14, 45, 32, -39], [13, -26, -11, -16, -39], [14, 49], [-17, 12], [36, -4], [14, 37, -2, -35, -10], [50, 47, -20]]
Output:
[20, -1728, 8, 0, 24, 448, 416, 14, 12, -144, 280, -1000]
