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: [[39, 18], [48, -12, -42], [44, -22, -8, -12], [-16, 21, -43], [13, 4], [-18, 43, 10, 40], [6, -33, 37, 39], [15, 4, -46, -30, -27], [13, -10, -8, 31], [36, -33, -47, 39, -18], [18, 31, -30, 24, -24], [-13, -34, 4, -16], [-15, -30, -36, 2], [-27, -32, -40]]
