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: [[18, 40, 13, -2, -25], [7, 13, -41, 11, -32], [6, 14], [40, 41], [22, 46, 14, 45, 2], [35, 9, -16], [48, 41, 47, -22, 25], [30, 22, 44, -33], [-34, -37, 3, -27], [44, -1, -35, -22], [1, 1, 29], [-49, 50, 40], [-14, -17, 6]]
