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: [[-42, -15], [37, 20, 12], [42, 39, -44], [-47, 24, -15, 24, -43], [37, 4, 17, -29, -35], [-44, -35, -3, 9, 3], [3, -45, 41], [-43, -19, -26, 26], [-10, -38], [21, 42, 46, -35], [28, -7, -23, 38, 29], [40, 11, -47, 37], [-49, -29]]

SOLUTION: [-42, 240, -1848, 576, 4, -44, 0, -676, 380, 1932, 1064, 40, 0]

PROBLEM: [[-49, 3, 15, 17, 0], [19, 38, -10, -31], [5, -34, 29, -20, -44], [-1, 48], [44, 49], [-35, 5, 7, -33]]

SOLUTION: [0, -380, -29920, 48, 44, 0]

PROBLEM: [[48, 45, -36], [-12, -31, 47], [-24, -14, 17, -48], [1, -1], [0, 8, 17, -31], [-5, 10], [2, -42, 24], [-37, -29], [-34, -5, 20, -19], [-6, 2]]
