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: [[-39, -14, 23, -37, 41], [-24, 49, -29, 38], [-49, -46, -8, -28, 0], [40, -29, 11, 20], [6, 13, -41, -34], [-26, -42, 2, -2], [-22, -11, 24, -35, -36]]

SOLUTION: [-14, -912, 0, 800, -204, -4368, 19008]

PROBLEM: [[13, 26], [42, -26, 21], [29, -39], [-24, 18, -17, -10, -17], [20, -3], [-15, -41, 17, -20, 16], [-6, 17, 14, -13, -4], [38, -39, 48, -46], [36, 1], [27, -45]]

SOLUTION: [26, -1092, 0, 4320, 20, -320, 336, -83904, 36, 0]
