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: [[-14, 50, 5, 50], [-49, -2, -30], [-35, 24, -20], [13, 0], [-29, -26, -44], [-11, 21, 48], [17, 22], [-41, 30, -11, -9], [32, -23, 40, 37, 11], [-37, 45, -35, -26, 17], [-39, 7, 48, -37, 14], [-13, 36], [-31, -31]]

SOLUTION: [-35000, 60, -480, 0, 1144, 48, 22, 30, 1280, -26, 672, 36, 0]

PROBLEM: [[-40, 39, 47], [32, -22, 29, 4], [-27, -11], [42, 26, 20, -12, 28], [-19, 46, 1], [-24, -38], [-32, 34, -44], [-1, 49], [-6, 42, 16], [2, 42, -29, 7, 22], [8, -47, -42, -20]]

SOLUTION: [-40, -2816, 0, -7338240, 46, 912, 47872, 0, -4032, 1848, 6720]

PROBLEM: [[0, -37, -33, 30], [46, 44, 25, 50], [-32, -16], [32, -5], [-34, -31], [-21, 26, 12, 46, 15], [7, 43, -12, -39, 23], [4, 28, 23, 15], [-38, 33, -33, 21], [-42, 44, -26, 38, 47], [-50, 32, -43, -1], [5, 10], [17, 12, -25]]

SOLUTION:
[0, 101200, 512, 32, -34, 14352, -12, 112, -38, 1825824, -1600, 10, 12]
