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: [[6, -17, 19, 42], [40, -6, 30, -4, -13], [-3, -42], [37, 39, 26], [-7, -23, 16, -15, 42]]

SOLUTION: [252, 28800, -42, 26, 672]
