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: [[9, -24, 11, -5, -8], [20, -9, 34, 1, -45], [-1, 38, 7, 6, 40], [15, 1], [48, 8, 47, -32, 9], [-7, -14, -26], [21, -21, -9], [-3, 33]]

SOLUTION: [192, 680, 9120, 0, -12288, 364, 0, 0]

PROBLEM: [[-45, 32], [-19, 12], [-5, 12, 29], [0, -13, 14, -38], [-2, -37, 16], [-9, 30, 38, 31, 47], [10, 45, -11, -6], [20, 47, 21, -18, 18], [6, 24, -31, 25], [41, -43, -42], [14, -25], [-7, 35, -7, 47], [46, -48, -33, 44, 37], [31, 49]]

SOLUTION: [32, 12, 12, 0, -32, 1140, -60, -6480, 144, -42, 14, 0, -97152, 0]

PROBLEM: [[43, -24, 26], [26, -31, 22, -2], [10, -4, 41], [32, -22, 50, 4], [-23, 5, -12], [0, 31], [13, 12, -17, 34, 48], [21, 35], [8, 48, 43, 48]]

SOLUTION:
[-624, -1144, -40, -140800, -12, 0, 19584, 0, 18432]
