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: [[27, 7, 13], [-42, 16, 17, -28, -40], [-19, -2], [-26, 18, 25, -16], [16, 50, -40, -33, 38], [-39, -42, 28, -27], [-37, 29, 3, -15, 13], [25, 38, -23, 33], [-28, -9], [-32, -22, 44, -15], [-3, 27, -24, 32]]

SOLUTION: [0, -752640, -2, 7488, -1216000, -1176, 0, 38, -28, 30976, -768]
