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: [[12, -14, 38, -45], [-4, 10], [2, 3, -18], [-12, 19, 39, 31, -5], [-36, -15, -1, -5, 16], [9, -49, -11], [2, 50, -39], [33, -31], [-15, -27, -10, 4, -45], [-45, 5]]

SOLUTION: [-6384, -40, -36, -12, -576, 0, 100, 0, -40, 0]

PROBLEM: [[10, 3, -49, 43], [-31, 14, -20, -3], [48, 2, 45], [-39, -23, -30], [43, 47, 11, 26, 5], [14, -40, -19, -41], [6, 0, 41, -42, 26], [43, -49, -50], [-21, -1], [39, -29, -45, 20]]

SOLUTION: [10, -280, 96, -30, 26, -560, 0, -50, 0, 20]

PROBLEM: [[-6, 42, 50, 29], [36, 12], [12, -25], [-5, -5, -36, -5, -27], [8, 34, 13], [-14, -3], [1, 34, -3, -36]]

SOLUTION:
[-12600, 432, 12, -36, 272, -14, -1224]
