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: [[-28, 14], [-9, 23], [-37, 17, -30, 30, -5], [37, -39, 29], [22, 2], [44, -39, -14, -46, 14], [31, -27, 17, -40, 36]]

SOLUTION: [-392, 0, -900, 0, 44, 396704, -1440]

PROBLEM: [[21, 22, -31, -12, 29], [44, 20, 0, 26], [1, -33, 50, 4], [47, -35, 50, -31], [49, -26, 47, -36], [-39, -28], [44, 2, 13, 41, -9], [4, -14, -9, -20], [24, 35, -24], [-30, 45, 23, -17], [-18, 38, -29, 29], [-50, 13]]

SOLUTION: [-264, 0, 200, 50, 936, -28, 88, 1120, -576, -30, -684, -50]
