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, 20, -17, 40, -35], [17, -45, 39, 43, -42], [12, -9], [18, 21, -29], [-27, -8, -18, -21, 15], [9, -33, -30, 21, 8], [-15, 39, 8], [-17, 13, -37, -10], [9, -33], [2, 10, 23, 41, 47], [17, 5, 6, -21, 16], [-44, -8]]

SOLUTION: [36800, -42, 12, 18, 144, -240, 8, -10, 0, 20, 96, 352]

PROBLEM: [[46, 38, -27, 16, -38], [34, -5, 25, 17, -45], [12, -14], [-9, -50, -11, 48, 2]]

SOLUTION: [-1062784, 34, -168, -4800]

PROBLEM: [[-7, 29, 1, 25, 3], [31, -31, 25, 14, 20], [-15, 28, -36, -17, 28], [50, 21, -14, 38], [35, -25], [20, 28], [-32, -43, 2], [-43, -34, -49], [12, 19], [-34, 9], [-48, -9, -11, -20, 20], [-24, -43, -24, -32, 37], [-41, 14, 22], [7, 17, -40, 9, 48]]
