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: [[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]
