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: [[-17, -21, 14], [-20, 36], [43, -42, -47], [48, 16, 2], [6, 47, 11, 24, 27], [-26, 49, -18, -14, 19]]

SOLUTION: [14, -720, -42, 1536, 144, -6552]
