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: [[-6, -27], [50, -8], [21, -43], [29, 45], [48, -25, -2], [22, 12, -49, -45, 20], [-9, 45], [-25, 17, -49, -43], [38, 12, -13, 49, -40], [40, -27], [1, 5, 18], [26, 47, -31, 21]]

SOLUTION: [-6, -400, 0, 0, -96, 5280, 0, 0, -18240, 40, 18, 26]

PROBLEM: [[9, -3, -35, -21], [20, 11, 39, 34], [17, 11], [6, -25, -48], [39, 8], [25, -1], [33, 47, 42], [-48, 39, 0, -47], [36, 36]]

SOLUTION: [0, 680, 0, -288, 8, 0, 42, 0, 1296]

PROBLEM: [[47, -41, -40, 4, -9], [-12, -17, 35, -50], [-50, -47], [35, 19, -31, -23], [0, -40], [-26, -24], [23, 26, -16, -22]]

SOLUTION:
[-160, 600, -50, 0, 0, 624, 9152]
