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: [[-38, 48, 1], [-4, -35], [28, 26], [34, 38, -46, 23], [-3, -47, -1, 32, -41]]

SOLUTION: [-1824, -4, 728, -59432, 32]

PROBLEM: [[4, 39], [-49, -6, 5, 41, 25], [-40, -45, -33], [28, -23, 45], [8, -32], [-8, -43, -4, -24], [-19, -43, 6, 2, -28], [35, -28, 37, 21], [45, 41], [-34, 27, 25, 5], [-23, -1]]

SOLUTION: [4, -6, -40, 28, -256, -768, -336, -28, 0, -34, 0]

PROBLEM: [[-30, 36], [26, 35], [-50, 34], [-6, -15, -31, 28], [-20, -32, 41], [30, 49, -31], [27, -20, 15]]
