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: [[-50, 2, 25], [-27, -18, 7], [-17, 6, 9, -35], [-34, 33, -48, 19], [-31, 9], [29, -29], [47, 5], [-1, 29, 26], [-23, -7], [26, -7, 40, 36]]

SOLUTION: [-100, -18, 6, 1632, 0, 0, 0, 26, 0, 37440]

PROBLEM: [[30, -24, -19, 29], [-1, -24], [26, 23, 27, 30, -23], [-17, 48, -43, 0], [40, -19, 21, 37], [37, -3], [-9, 24, 23, 36, -32], [-46, -13]]

SOLUTION: [-720, -24, 780, 0, 40, 0, -27648, -46]

PROBLEM: [[-2, 45, 15, -35], [-16, 41, -44, -3], [-20, -6, -42, -13, 12], [15, -49, 13, 46], [7, -31], [9, -7, 18], [-40, 16, -23, 5], [-50, -43, -45], [23, -19, -25, -19], [42, 15, -15, -49, -27]]
