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: [[-17, -32, 48, 22], [-43, -46, -11, 20], [-14, 42, -28, 10], [0, 19, -24, -25], [-19, 38], [26, 4]]
