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, -22, 8], [-9, 49, -1], [-26, 18, -19], [6, 26, 30, 39, -32]]

SOLUTION: [-176, 0, -468, -149760]

PROBLEM: [[-42, -43, -28, 45], [-27, 20, 46, -25, 9], [40, -46, 29], [19, 42], [-5, 30, 30], [14, 47, 13, 35], [-15, -29, 39, 0], [26, -44]]

SOLUTION: [1176, 920, -1840, 42, 900, 14, 0, -1144]

PROBLEM: [[12, -32, -12, 41, -38], [10, 20], [46, -22], [8, -6, 35], [-5, 17], [-22, -12], [-21, 27, 20, 13], [43, -9, 47], [-15, 36, -37, -24, 1], [12, 7, 6, 4, 41], [41, 4, 38, -39], [-34, -43, -2, 2, -28], [19, -48, -11, -22, -28]]
