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: [[-24, 26, 13, 37], [-5, -23, -15, -49, 29], [45, 47], [8, 10]]

SOLUTION: [-624, 0, 0, 80]

PROBLEM: [[26, 24, -42, 4, -8], [50, 25, 3, -46, -27], [37, 47, -10, -1], [-39, 1], [-31, 10, 29, -14], [7, -21, -18], [7, -19, -17, -16], [-9, -44, 40]]

SOLUTION: [838656, -2300, -10, 0, -140, -18, -16, -1760]
