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: [[23, -48, -18], [9, 47, 33, 32, -22], [-30, -23, 9, -25, -17], [-39, 8, 27], [3, -34, 8, -42]]

SOLUTION: [864, -704, -30, 8, 11424]

PROBLEM: [[-5, -23, -21, 27, 14], [-20, -49, -16, -22, -27], [-6, 1, -9], [-14, -31, 20, 2, 23], [18, 0, 41, -46], [35, 11, 34, 11, 38], [-21, -32, -20], [-33, 21, 12, -46, 14], [-7, -36], [-26, -44, 47], [-4, -16, 4, -19, 9], [-30, 30, -3, -45], [24, 40, 48, 2, -38]]

SOLUTION: [14, -7040, -6, -560, 0, 1292, 640, -7728, -36, 1144, 256, -900, -3502080]
