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: [[-15, -40], [-10, -38, 23, 2, -11], [-1, 37, -27, -48], [-33, -5, 13, -22, 10], [31, -7, 45], [48, -29], [26, 0], [36, 20, 33, 43], [6, -18, -39], [37, -37], [-16, -25, -15], [-28, -23], [10, -30, -38]]

SOLUTION: [-40, 760, -48, -220, 0, 48, 0, 720, -108, 0, -16, -28, 11400]

PROBLEM: [[25, -34, 40], [15, 37, -35, -42], [48, 26, -7, 30, -2]]

SOLUTION: [-1360, -42, -74880]

PROBLEM: [[-28, 4], [-17, 4], [-50, 44], [12, 14], [35, -42, -4, 39, -42], [34, 18, 43, -26], [1, -29], [4, 15, 29], [-49, -43, -26, 10], [-44, -39, 3, 48], [37, -20, 8, 4], [27, -25, 15, 16], [-12, -20, 17]]

SOLUTION:
