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: [[-1, -44, 39, -18, -27], [-46, 10, -47], [4, 24, -38, -25, 19], [-12, 4, -43, 46, 34], [-21, 22, -17, -49], [-40, 17, -12], [-8, 45], [-39, -23], [0, 12, -34], [46, -5, -47, -4, 6]]

SOLUTION: [792, -460, -3648, -75072, 22, 480, -8, 0, 0, -1104]
