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: [[1, -32, -10], [50, 4], [39, 12, -16, 10], [17, 27, -44], [-6, 13], [13, 40, -25, -14, 40], [-43, -32, -30, -13], [44, 18, 34, -18, 9], [-9, -2, -15, 23], [-37, -19, -24, -36], [-2, -44, 16], [-35, -30, -2, 29, -31]]

SOLUTION: [320, 200, -1920, -44, -6, -22400, 960, -484704, -2, 864, 1408, 60]

PROBLEM: [[22, 40], [15, -7, -5, 23, -4], [-34, -17, -22, 45], [40, 28], [16, -1]]

SOLUTION: [880, -4, 748, 1120, 16]

PROBLEM: [[-49, 28, -45, -39], [13, 0, -17, 7], [14, 10, -46], [6, 1, 1], [-20, 23, -25, 47], [-9, -20, -36, -38, 41], [46, -37, -45, -31], [-37, 49, 42]]

SOLUTION:
[28, 0, -6440, 6, -20, -27360, 46, 42]
