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: [[49, 13], [32, 46], [32, -27, 10, 3, -15], [-45, -47], [-46, -28, 21]]

SOLUTION: [0, 1472, 320, 0, 1288]

PROBLEM: [[-20, 41], [50, 25], [11, 23, -32, 42, -10], [-38, 37, 36, 44], [-12, -25, -30], [-50, -21, -43, 33], [-13, -5, -5, 3], [18, 8, -11, 13, 3], [-26, 8, -33, -17], [35, 44, 49, -32], [30, 33], [-42, -46, -4, 25, -28], [-31, 30, -43, -2], [19, 43], [-31, -35]]
