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: [[-42, -27, 44, 0], [20, 5, -19], [-22, -2, 15], [-1, 6, 27, -22], [-13, -39], [-11, -14, 46], [-47, -16, -50], [-35, -9, 8, 12], [44, -19, -1, 34, -27]]

SOLUTION: [0, 20, 44, -132, 0, -644, 800, 96, 1496]

PROBLEM: [[-37, -34, 13], [-34, 0, 38], [2, -12, 33, 30, 25], [-19, 21, 21, -25, 48], [2, -6, -29, -9, 19], [-23, -50, 30, -24, -47], [-32, -16, 17, -22, 14], [-42, -2], [-36, 29, 32, -37], [-46, 16, -26, -43, -47], [-17, 45, 4, -18], [29, -5, -29]]

SOLUTION: [-34, 0, -720, 48, -12, 36000, -157696, 84, -1152, 19136, -72, 0]

PROBLEM: [[20, 25], [-48, -6, -39, -43], [-40, -33, -32, 45], [-28, 15, 47], [-21, -12], [-14, -10, -4, 13], [-26, -5], [26, 25], [-11, -11, -44, 9, 44], [-13, 43, -23]]

SOLUTION:
[20, 288, 1280, -28, -12, -560, -26, 26, -1936, 0]
