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: [[13, 26], [42, -26, 21], [29, -39], [-24, 18, -17, -10, -17], [20, -3], [-15, -41, 17, -20, 16], [-6, 17, 14, -13, -4], [38, -39, 48, -46], [36, 1], [27, -45]]

SOLUTION: [26, -1092, 0, 4320, 20, -320, 336, -83904, 36, 0]

PROBLEM: [[14, 24, -49, -21], [-8, -48], [-17, -2, 23, 20], [21, -14, 13, 35], [-33, -48, 47, 6], [38, 42, 47, -9]]

SOLUTION: [336, 384, -40, -14, -288, 1596]

PROBLEM: [[-15, -18], [-27, 44], [-18, 34, 43, -24]]

SOLUTION:
[-18, 44, 14688]
