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: [[0, 43, 10, -26], [-28, 12, -40, 29, 11], [-5, -26, 28, -17]]

SOLUTION: [0, 13440, -728]

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: [[42, -31], [23, -35, -36], [30, 19, -20], [-8, -29], [41, 2], [-43, -49, 49, -17], [-26, 5, 2, 16, -13], [1, -42, 30], [27, 18], [-46, 7, 14], [24, -9, -49, -37], [36, -24, -36, -39], [-29, -33], [-41, 9, -16]]

SOLUTION:
[42, -36, -600, -8, 2, 0, -832, -1260, 18, -644, 24, 31104, 0, -16]
