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: [[-37, -41, 17], [29, -44, 35, -34, -46], [26, 9, 28], [0, -16, 24, -18], [13, 18, 42], [29, -21, -27], [-10, -16, 12, -39, -22], [4, -3], [-29, -23]]
