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: [[-37, -20, 18, -43, 7], [-49, -13, 11], [-29, -31], [-9, 6, -6], [3, 44, 33, -15, 20], [31, 20, 4, 49, -22]]

SOLUTION: [-360, 0, 0, -36, 880, -1760]
