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: [[1, 17], [29, -35, -18, -6, 9], [39, 0, -30, -12], [44, 46]]

SOLUTION: [0, 108, 0, 2024]

PROBLEM: [[6, 46, -23, 27], [29, -43, 9, 42, 44], [-34, 5, -10], [-12, 14, 48, 22], [19, 35, -46, -48], [-43, -32, 21], [48, 40, -39, 48], [-3, 11, -46], [37, -37, -7], [4, 4, 50, -37]]

SOLUTION: [276, 1848, 340, -177408, 2208, -32, 92160, -46, 0, 800]

PROBLEM: [[-7, -28], [-12, 32, 3, -13, 16], [6, 41], [0, 1, -25, -20], [19, 12, 45, 29, -25], [-26, -16, -22, -35, 32], [-49, 43, 23, 9, 12], [-38, 50, -8, 50], [-50, 25], [-12, -9, 39, -48, -46], [-23, -39]]

SOLUTION:
[-28, -6144, 6, 0, 12, -292864, 12, 760000, -50, -26496, 0]
