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: [[-50, -21, -39, -32], [-24, 13], [-43, 13, -16, 21], [-36, -30], [45, -15, -2, -15], [-11, 30], [-43, -31], [17, -49, 37, 27], [-13, -35, 28], [-2, 10, -42], [-39, -5, -5, -14], [16, 38]]
