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, -29], [-11, 14], [-21, 9, -16, -22, 13], [46, -5], [-6, -35], [-48, 45, -25], [-33, 3, -41, 12, -45], [-21, 16, -8, -27], [14, 49], [40, -3]]

SOLUTION: [920, 14, 352, 46, -6, -48, 12, -128, 14, 40]

PROBLEM: [[-40, 39, 47], [32, -22, 29, 4], [-27, -11], [42, 26, 20, -12, 28], [-19, 46, 1], [-24, -38], [-32, 34, -44], [-1, 49], [-6, 42, 16], [2, 42, -29, 7, 22], [8, -47, -42, -20]]

SOLUTION: [-40, -2816, 0, -7338240, 46, 912, 47872, 0, -4032, 1848, 6720]
