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: [[8, 39, -35, 42, 28], [41, -30, 28], [-7, -2, 0, 18, -29], [38, -8, -2], [35, 8, 39, 46], [29, 19, -42], [3, 37], [16, 47], [-9, 39, 41, -48, 23], [-16, -50, -42]]

SOLUTION: [9408, -840, 0, 608, 368, -42, 0, 16, -48, -33600]

PROBLEM: [[-2, 41, -50, -30], [5, -47], [35, 6, -46, 21], [33, 23, -6, -26], [-46, -15, -2], [-16, 29], [-20, -12, -20, -50]]

SOLUTION: [-3000, 0, -276, 156, 92, -16, 240000]

PROBLEM: [[-3, -25, 29, -18, 29], [-45, -48, -41, 28], [26, -44, -24], [0, 50, -45], [7, -20, -3, -50], [-28, 3, -6, -4], [-2, 40], [0, -41, 6], [6, 21, 8, -11], [-37, -17, -3], [37, -7, -18, -33], [-2, 17, -45]]
