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: [[9, 33, 23], [43, 23, 8, 35, -12], [-43, -34, 15], [35, 29, 39, -3], [7, 15, 22, 12, 40], [-16, -11, -35, -38], [-28, -13, -40], [30, 43, 25, 8, 49], [-8, -6, 9, 21, -18], [-14, 1, -11, -26], [19, -19, 49, -5, -48], [-26, -22, -17, 27], [11, 48, -44, 15, 7]]

SOLUTION: [0, -96, -34, 0, 10560, 608, 1120, 240, -864, 364, -48, 572, -2112]

PROBLEM: [[4, 39], [-49, -6, 5, 41, 25], [-40, -45, -33], [28, -23, 45], [8, -32], [-8, -43, -4, -24], [-19, -43, 6, 2, -28], [35, -28, 37, 21], [45, 41], [-34, 27, 25, 5], [-23, -1]]
