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: [[49, -7, 25, 42], [10, -10], [-22, 26, -34, 18, 6], [-34, 9, -33, 22, 45], [-14, -20, -13, -9], [14, 38, -45, -15, -10], [-28, 2, -27, 38], [-21, -49, -34, -13, 30], [16, 49, 48, 38], [2, 9, 13, 0, -5], [-27, -6, 16, -5, 46], [2, -43]]

SOLUTION: [42, -100, 2100384, -748, 280, -5320, -2128, -1020, 29184, 0, -4416, 2]

PROBLEM: [[31, -19, 33], [16, 10], [-32, -36, -23]]

SOLUTION: [0, 160, 1152]

PROBLEM: [[-19, 10, -15, -9, 4], [2, 31], [-31, -17, -49, 13], [40, 42, -22], [14, -28, -47], [36, -22], [20, 23, 8, 0], [2, -47, -39, -9, 27], [34, -20, -19, 11, 11], [37, 19, 22, -9, 44], [-5, -18, 9, 7, 29], [1, -20], [1, 7, 43, -19]]

SOLUTION:
[40, 2, 0, -36960, -392, -792, 0, 2, -680, 968, -18, -20, 0]
