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: [[22, 22, 49, -31], [-24, 10, 28], [-12, 44, -17, -35, 28], [-10, 35, 20], [16, 1, 13], [6, 15, 23], [35, 42, 1], [7, -26]]

SOLUTION: [484, -6720, -14784, -200, 16, 6, 42, -26]

PROBLEM: [[-50, 49, -28], [-50, 39, 21, 44, -18], [-29, 5, 14, -7], [-13, 10], [27, -45, -14, -10, -36], [-41, -35, -48], [-25, -26, 38], [-7, -32, -35, 7, 48], [-6, -34, -28, -2], [-27, -24, 47, 30, -35], [22, -1, 49, -2, 38], [-31, 29], [4, -49, -46, -36, -14], [-40, 22], [-36, 19, -10, -45, 10]]
