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: [[26, 22, -22, -41], [-27, -30, 35, -49], [44, 10], [30, 5, -47, 37], [25, -15, 48], [-42, -21], [41, -48], [19, 18, -10, -4]]
