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: [[46, 46], [1, -11], [-10, 6, -11], [-32, -37, -50, 31]]

SOLUTION: [2116, 0, -60, 1600]

PROBLEM: [[-11, 19, 27, 12], [11, 23, 50, 46], [43, 2], [26, 21, -48, -42, -15], [38, 42, -2], [41, -27, -37, -18, -4], [37, 22], [-19, 32, 44], [-36, -16, 49, 40], [-26, -21, 6], [-40, 1, -42, 10, -26], [34, 30], [5, -27, -48, -35, -20], [46, 32, -9, -32]]
