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: [[-41, 42, 42], [-42, -21], [-3, -33, -8, -11, 28], [43, 20, -27], [40, 42, 30], [16, 10], [-11, 29, 48], [-32, 13, -50], [-26, 3, 2], [3, 15, 35, -33], [0, -18, 38], [-2, 11, 35], [6, 26, 46], [-11, 41, -7, -44, -15], [46, -40, 4, 12, -23]]
