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: [[-16, -14, -26, -12], [46, -49, 3, -17], [-21, -2, 45, -12], [-26, 35, 1, 43], [-7, -39], [-18, -26, 2, 4], [0, -18, -15], [42, 0], [-27, 35, 38, 8, -33], [-20, 7], [44, 8, 15, 42, -14], [-28, 49, -5, -39, -24], [4, -13, -2, -7, 20], [21, -29, -6, 43, -11], [-14, 26, 19]]

SOLUTION: [69888, 46, 24, -26, 0, 3744, 0, 0, 304, -20, -206976, 672, -160, -6, -364]

PROBLEM: [[-6, -22], [41, -1, 11, -12], [-41, 25, 20, -43], [20, -3, -40, -25, 18], [28, 0], [-49, 31, 30, 10, 14], [3, -16, 42, -2, -7], [6, -27, -33]]

SOLUTION: [132, -12, 20, -14400, 0, 4200, 1344, 6]

PROBLEM: [[46, -9, -37], [-21, -19, -9], [50, 19, -6], [7, 28, 20, 26, -5], [-46, 28, -1, 24, -30], [9, -34], [-42, 46, -46, 23, -33], [38, -16, 42, 8], [-26, 27, -43, -29, 33], [12, -27, 0, 0], [-10, 27, 6, 43, 9], [-40, -39, 32, 44]]

SOLUTION:
[46, 0, -300, 14560, 927360, -34, 88872, -204288, -26, 0, -60, -56320]
