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: [[31, -12, -45, 3, 50], [-38, -34, -10, 2], [-17, -29, -2, -10, -15], [-1, -13, -24, 48, 25], [-33, -29, 13, 41], [-19, 42, 26, 40], [21, 3], [30, -13, 20]]

SOLUTION: [-600, -25840, 20, -1152, 0, 43680, 0, 600]
