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: [[-29, -40, -45, -11, 8], [-44, -42, -37, -7], [0, -12], [25, -48, -44, 14], [12, -44, 27], [13, -46, -27], [34, -20, 29]]

SOLUTION: [-320, 1848, 0, 29568, -528, -46, -680]

PROBLEM: [[-8, -47, 38, 16], [-8, 10, -29, 34], [-9, 29], [17, -30, 31, 11], [28, 16, 33, -29], [-28, -35, -47, 14], [50, 34, -15], [-36, 23, 1, -31, -29], [41, 46, 1], [-29, -16, 10, 12, 43], [-25, -22], [4, 49], [-23, -7, 27], [50, 35], [-19, -30, 8, 15]]
