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: [[-15, -22], [-20, 45, 0], [10, -47, -17], [39, -32], [50, 3, 44, 44, -7], [13, -20, 36, -11], [-5, -11, 4], [24, 27, 50, 4], [28, -30], [-36, 25, 17, -24, 35], [-44, 33, 46, -24, 21], [-3, 21, 38], [-23, -28, 42, 11]]

SOLUTION: [-22, 0, 10, -32, 96800, -720, 4, 4800, -840, 864, 48576, 38, -1176]

PROBLEM: [[-26, 40], [-21, -24, -50, -37], [46, 2], [5, -45, -32], [-5, 16, -24, 30], [-21, 12], [14, 43], [-27, -34, -27], [-31, 20, -24, 0, -33], [22, 34, -4, -9, -34], [43, 40]]

SOLUTION: [-1040, 1200, 92, -32, -11520, 12, 14, -34, 0, 101728, 40]
