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: [[-5, 30, -4, 25], [2, -7], [45, -31, -16], [21, -23], [-43, 46], [-24, 44, 33, -28], [8, 0, -14, 4, -2], [-13, 40, 23, -17, 40], [-28, 19, 25, 38], [18, -16, -32, -47]]
