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: [[-36, 13, 37, -31], [-3, -10], [18, 17, 36], [-11, 35, 27, 30, 37], [4, 8], [31, 38, -26], [-29, 5], [9, 14, 37, -17], [28, 47, 24, -20, -21], [21, -13]]

SOLUTION: [-36, -10, 648, 30, 32, -988, 0, 14, -13440, 0]
