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: [[-8, -1, -12], [38, 17, -12], [35, -40, -6], [-5, -15, 43, -42], [-46, -38, 46, -49, 30]]

SOLUTION: [96, -456, 240, -42, 2412240]

PROBLEM: [[31, 35], [-31, -49, 14, -23, 16], [37, -39, -8, -28], [-30, -8, 32], [-36, -30, 7, -39, 37], [5, 13, -15], [17, -39], [-14, -11, 46, 21, 25], [-21, 40, 34, -39, 0]]

SOLUTION: [0, 224, 224, 7680, 1080, 0, 0, -644, 0]
