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: [[-5, 29, 5, 36], [36, -42], [36, -14, 49, 28, -33], [-39, 4], [-46, 44, 37], [-10, -36, -35, 24], [7, 10], [28, 23, 30], [-42, 4, -50], [-1, -2, 50], [-3, -42, 3], [-5, -45, 28], [-43, -8, -18], [-37, -42, 17], [30, 32, 39]]

SOLUTION: [36, -1512, -14112, 4, -2024, 8640, 10, 840, 8400, -100, -42, 28, 144, -42, 960]

PROBLEM: [[-17, -33, 27, 45, -50], [10, 18, 25, 21], [20, -7, 10, -10, 19], [-8, -18, -11]]

SOLUTION: [-50, 180, -2000, 144]

PROBLEM: [[20, -13, 45, -10, 20], [34, -21, 0, -10], [-9, -29, 0, 36, -12], [-22, -43, -9, -24], [-12, -32], [-50, 14, -29, 43, 2], [-43, -50, 26], [-34, -12], [30, 38, 3, -9], [8, 17, -18, -41, -5], [34, 26, -46], [21, -22, 7, 12, -47], [3, 21, 29, 43], [-46, -39], [-33, -28, 17, -7]]

SOLUTION:
[-4000, 0, 0, 528, 384, -1400, -1300, 408, 1140, -144, -40664, -264, 0, -46, -28]
