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: [[34, -2, -41, 25, -45], [-47, 42], [-2, 26, 36], [36, 27, -9, 17]]

SOLUTION: [-68, 42, -1872, 36]

PROBLEM: [[18, -11, -13], [-20, -21, 26], [40, 6, 3]]
