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, 46, -20], [36, -9, 24, 43, -5], [-45, 7], [29, -3, -23, 47, 23], [-12, -6], [40, -32, 4], [-17, -30, 13, 9]]

SOLUTION: [-920, 864, 0, 0, 72, -5120, -30]

PROBLEM: [[-18, -11, -44], [29, 37, -44, 5], [46, 25], [11, 25, -37, -18], [22, -43, 38, -28, 1], [6, 11, 4, -1], [-44, -17, 35], [-43, 15, 47, -28, 8], [1, -24, 19, -22, -20], [-17, -13, -44, 20], [23, 23, 17, 25, -32], [-23, 39, -39, -11], [26, -24, -18, -50, -40], [-28, 18, -8, -4], [12, -20]]

SOLUTION: [792, -44, 46, -18, -23408, 24, -44, -224, -10560, -880, -32, 0, 22464000, -16128, -240]

PROBLEM: [[42, 43, -50], [-11, -40, -34, 0, -20], [3, 35], [-44, -3], [-38, 23], [-43, -49, 11], [-34, 46], [-29, -37, -30, -10], [-17, -16, 46, -18, 30], [-29, 3, -35], [5, -50, -21]]

SOLUTION:
[-2100, 0, 0, -44, -38, 0, -1564, 300, 397440, 0, -50]
