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: [[-18, -11, -44], [29, 37, -44, 5], [46, 25], [11, 25, -37, -18], [22, -43, 38, -28, 1], [6, 11, 4, -1], [-44, -17, 35], [-43, 15, 47, -28, 8], [1, -24, 19, -22, -20], [-17, -13, -44, 20], [23, 23, 17, 25, -32], [-23, 39, -39, -11], [26, -24, -18, -50, -40], [-28, 18, -8, -4], [12, -20]]
