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, -26], [-26, 23, -3, -25, 5], [-28, -15], [45, -6, 12, 49, 45], [31, 22, -11], [41, -34, 18, -7, 31], [43, 23, -49, -34], [27, 0, -39, -40, 27], [-27, -4, -3, -32, -35], [-32, 11, 24, 11, -35], [42, -10, -43, -37], [-43, -2], [-28, -38, -17, 34, 19], [-46, -10]]

SOLUTION: [-26, -26, -28, -72, 22, -612, -34, 0, 128, -768, -420, -2, 36176, 460]

PROBLEM: [[8, -27, 49, -40, -35], [-25, -28], [-16, 46, 2, -33, -48], [-49, -15], [-14, -18, -27, 27], [27, -15, 24, 17], [20, -17, 19, 19], [15, -19, 7, 32, 25], [1, -46, -15, 41], [-35, 14, 32, -16], [0, -9, -5, 16]]
