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: [[43, 48, 42, -12], [27, 42, 48, 27], [-6, -17, 9], [17, 4], [-40, -46, -14, -13], [-2, -47], [11, -38], [2, 19], [-39, -12, -28], [22, -2, 47, -38, 49], [0, 47, -25, -44], [-21, -43, -49, 46, -8], [-24, -47]]
