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: [[46, 20, -29], [-11, 14], [-21, 9, -16, -22, 13], [46, -5], [-6, -35], [-48, 45, -25], [-33, 3, -41, 12, -45], [-21, 16, -8, -27], [14, 49], [40, -3]]

SOLUTION: [920, 14, 352, 46, -6, -48, 12, -128, 14, 40]

PROBLEM: [[-21, -32, 1], [19, 31, -9, 40, 24], [49, -12, -36], [1, -17, -4, -47, 30], [-29, -38, -36]]

SOLUTION: [-32, 960, 432, -120, 1368]

PROBLEM: [[22, -27, -7], [48, -30, 12, 33], [-6, 22, 20, 50, -45], [27, 0, 46], [-26, -8, -4, -30]]

SOLUTION:
[22, -17280, -132000, 0, 24960]
