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: [[31, 22, 2, 35], [7, -27, -3, 37], [-46, 34], [-33, 42, 28, 8]]

SOLUTION: [44, 0, -1564, 9408]

PROBLEM: [[-5, 2], [22, 16], [33, 6, -36, -35], [-20, 1, -35, 25], [-32, 10, 41], [-45, 32], [38, 50, 47, 9], [-50, 50, -5, 29], [-11, -8, 42, -45], [30, 44, -43]]

SOLUTION: [2, 352, -216, -20, -320, 32, 1900, -2500, -336, 1320]

PROBLEM: [[17, -39, 44], [5, -40, 1], [-37, -30], [-46, -4, 26, -5, -22], [28, 22, 9, 36, -48], [45, -24, -4, 15], [38, -30], [-7, -29], [-16, -17, 19], [-8, 36, 50], [-48, 1, -10], [8, -50, -2], [25, -18]]

SOLUTION:
[44, -40, -30, -105248, -1064448, 96, -1140, 0, -16, -14400, 480, 800, -18]
