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: [[8, -27, 49, -40, -35], [-25, -28], [-16, 46, 2, -33, -48], [-49, -15], [-14, -18, -27, 27], [27, -15, 24, 17], [20, -17, 19, 19], [15, -19, 7, 32, 25], [1, -46, -15, 41], [-35, 14, 32, -16], [0, -9, -5, 16]]

SOLUTION: [-320, -28, 70656, 0, 252, 24, 20, 32, -46, -7168, 0]

PROBLEM: [[-41, 14, -34], [17, -4], [27, 42, 30, 19, -8]]
