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: [[-30, -2, 30, 1, -2], [26, -44, -48, 43, 43], [-22, -14, -38, -40], [-36, 8, 23, 3, 37], [14, -49], [15, 4, 44], [18, -22]]

SOLUTION: [-3600, 54912, 468160, -288, 14, 176, -396]

PROBLEM: [[50, -16, 48], [50, -37, -8], [-39, -39, -40, -3, 12], [35, -15, 29, -24], [49, -5, -42, 24]]

SOLUTION:
[-38400, -400, -480, -24, -1008]
