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: [[29, 40, 15], [34, 17, 34, -26], [-9, -13, 42, 42], [13, -1, 3, -22, -14], [-35, 19, -17, -48]]

SOLUTION: [40, -30056, 1764, 308, -48]

PROBLEM: [[-22, -12, -43, -8], [-46, 34, -18, 11], [-48, -8], [-16, -7, 50, -38], [12, 46, 32], [0, -25, -37, -7, 24], [-41, 1, -10], [14, 13, -10]]

SOLUTION: [-2112, 28152, 384, 30400, 17664, 0, -10, -140]

PROBLEM: [[21, -33], [-23, -15], [33, -13, 44, 9], [-47, 11], [3, 42], [-34, 27, 37, -8, -36], [-34, -40], [12, 18, 38], [-15, -8, -16], [14, -50], [-39, -5, 34, 16, 36], [17, -28, 22, -1]]

SOLUTION:
[0, 0, 44, 0, 42, -9792, 1360, 8208, 128, -700, 19584, -616]
