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: [[2, -22, 0], [-2, -36, 29], [9, -44, -36, -32, 18], [-49, -13], [8, 1]]

SOLUTION: [0, 72, -912384, 0, 8]

PROBLEM: [[16, 48, -44, -49], [44, -25, -39], [-8, -39, 30, 4], [15, -14, 1, -50, -11], [-20, -33, 10], [-29, -32, 48, 32, -29], [49, -35, 6, -39, -45], [9, -19]]

SOLUTION: [-33792, 44, -960, 700, -200, -49152, 6, 0]
