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: [[-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]
