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: [[-18, -5], [29, -9, -34], [4, 13], [-24, -27], [-43, -2]]

SOLUTION: [-18, -34, 4, -24, -2]

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: [[1, 24], [-34, -29, 29, 5, -38], [-32, -42, -39, 38], [-17, 43, -37], [9, -47], [11, -29, -34, -12], [-4, -33, -42], [-23, 39, -8], [27, 36], [-21, 24, 47], [-42, -43, 34, -31], [45, -26, 34], [8, 18], [-38, -18, -12, 9, 23]]

SOLUTION:
[24, 1292, 51072, 0, 0, 408, 168, -8, 36, 24, -1428, -884, 144, -8208]
