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, -47, 13], [-20, 29, 21, 33, 9], [-29, 28, 29, 24], [39, -10, 3], [12, -8, 9, 36], [3, -43, 47, -13, -8], [-40, -25, 38, 5], [-41, -13, 17], [47, 15, -16, 21], [-7, -47], [4, -47, -16, -3], [-46, 48, 39, 46, -31], [-47, 10, -35, -8], [31, 13, 35], [33, 47, -13, -4, -31]]

SOLUTION: [-18, -20, 672, -10, -3456, -8, -1520, 0, -16, 0, -64, -101568, -80, 0, -4]

PROBLEM: [[26, -33, 44, -50, -6], [11, -24, -46, 48], [-29, -38, 2], [-10, -39, -30], [41, -46], [17, 22, 11, -45], [-2, 27, 20], [-5, 41, 24, -43]]

SOLUTION: [343200, 52992, -76, 300, -46, 22, -40, 24]
