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: [[18, 15, -11], [23, -31, -1, 2], [44, -32, -12, 47, -47], [33, 26, 15], [30, 20, 16], [-43, -28], [-10, -49, 25, -1, 9]]

SOLUTION: [18, 2, 16896, 26, 9600, -28, -10]

PROBLEM: [[-11, 26, -48, -18, -14], [-32, 10, -27, 15, -1], [-10, 9, 33, -46], [-4, 1, 40]]

SOLUTION: [-314496, -320, 460, -160]

PROBLEM: [[-46, -37], [-27, -21], [-38, -30, 11, -47], [-27, 4, -7, -34], [-22, 0, -12], [-16, -11, -12], [-3, 11, -2, 33, -1], [-49, 46, 31, 43]]

SOLUTION:
[-46, 0, 1140, -136, 0, 192, -2, 46]
