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: [[24, 36, 0, 12], [1, 38, 18, -34], [-3, 26, -7, -11, 11], [6, -46, 9, -28], [43, 25, 36, 22, 39], [-50, 8, 24], [32, -12, -4, -45, 4], [-27, -25], [49, 17, -29, 31], [-43, -44, 36, 15, 5], [-19, -20, -50]]
