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: [[46, 1, -47, 6, 21], [-32, -37], [18, 14, -31], [28, 42], [-17, -14, -38, 34, -32], [27, -50, 27, -44, 35], [-37, 1], [-1, 1, -20, -24], [43, -19, -5, -38, 40], [-36, 48, -10]]
