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: [[30, -10, 13, 27], [16, -31, -26, 12, -6], [14, 49, 15, -31, -21], [-30, -11, 49, -36], [15, -27], [27, 5, 29], [-4, 47, 13, 6], [-3, 0, 11, 2], [12, 27]]

SOLUTION: [-300, 29952, 14, 1080, 0, 0, -24, 0, 12]

PROBLEM: [[-39, -5, -8], [-46, -42], [17, 14, -32, 37], [45, 42], [1, -25], [-33, 48, -33, -48]]

SOLUTION: [-8, 1932, -448, 42, 0, -2304]

PROBLEM: [[-47, -2], [-34, 32, 17, -22, 2], [-43, -30, -38, -5, -50], [34, -39, -23], [-16, -23, -4, -6], [-19, 7, -5], [15, 18, -31], [-12, 10, 42, 16, 28], [-2, -45, -12, -8, 29], [-27, -6], [36, -42, 35, -34], [-39, -15, -14, -37], [28, 31, -24, -41], [17, -50, -48, 18]]

SOLUTION:
[-2, 47872, -57000, 34, -384, 0, 18, -2257920, -192, -6, 51408, -14, -672, 43200]
