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: [[10, 46, 6], [-6, -18, -31, -15], [8, 25, -8, -4], [-5, -25, -41, -14], [20, 37, -17], [39, 19, 37, -34, -14], [-12, 42], [37, -48], [2, -5, -27, -7, 13], [-42, 29, 38], [-22, -44, 41], [13, -23, -31], [-19, 4, 14, -27]]
