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: [[19, -31, 34], [-24, -21, 48, -33], [26, 33, 29, 17, 5], [-41, 29, 46], [-20, 16, 50], [-8, 49, 4, -42], [-1, -27, -23, 11, -25], [-23, -45], [-26, 16], [45, 5, -9, -27], [-22, 38, 15], [-41, 49, 47, -50], [47, 9], [-17, -33]]

SOLUTION: [34, -1152, 26, 46, -16000, 1344, 0, 0, -416, 0, -836, -50, 0, 0]

PROBLEM: [[-45, 32], [-19, 12], [-5, 12, 29], [0, -13, 14, -38], [-2, -37, 16], [-9, 30, 38, 31, 47], [10, 45, -11, -6], [20, 47, 21, -18, 18], [6, 24, -31, 25], [41, -43, -42], [14, -25], [-7, 35, -7, 47], [46, -48, -33, 44, 37], [31, 49]]

SOLUTION: [32, 12, 12, 0, -32, 1140, -60, -6480, 144, -42, 14, 0, -97152, 0]

PROBLEM: [[5, -24, -4], [-20, -15, 42], [-8, -37, 11, 37]]

SOLUTION:
[96, -840, -8]
