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: [[9, -3, -35, -21], [20, 11, 39, 34], [17, 11], [6, -25, -48], [39, 8], [25, -1], [33, 47, 42], [-48, 39, 0, -47], [36, 36]]

SOLUTION: [0, 680, 0, -288, 8, 0, 42, 0, 1296]

PROBLEM: [[-5, 38, -48, 18], [-1, -1, -28, 27, 31], [26, 32, 2, -20], [14, -24, -19, -9, -28], [34, -35, 43], [-17, 6, 47], [41, 1, -13, -30], [41, 37, -17, -8], [-7, -39, -26], [-44, 36, 44], [-12, 11, -2, 12], [-35, 23, -24, -5, 49]]

SOLUTION: [-32832, -28, -33280, 9408, 34, 6, -30, -8, -26, -69696, 288, -24]

PROBLEM: [[-49, 38, -41, -7, -8], [38, 30, 44], [12, 49, 14], [-49, 4, -22], [47, 39, 37], [14, 46, 36, -46], [36, 37, -8], [11, 11, 27, 21, -35], [27, 50, 48], [48, -48, -12], [-28, -26, 17], [-11, 0], [15, 19, 50, -1], [39, 16], [-2, -23]]

SOLUTION:
[-304, 50160, 168, -88, 0, -1066464, -288, 0, 2400, 27648, 728, 0, 50, 16, -2]
