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: [[41, -50, 6, -16], [-16, -11, 12, -20, 14], [-39, -21, -43], [-34, -37, -6, -2, 23], [-3, -30, -39], [28, 28], [42, 15, -8, -19], [-41, 29]]

SOLUTION: [4800, 53760, 0, -408, -30, 784, -336, 0]

PROBLEM: [[18, 17], [-48, 16, 17, 1], [-14, 26, -17], [17, 49, -30, -42, 26], [-20, 16, -4, -5, 4], [-39, 23, -37, -25], [24, -40, -23, -4]]

SOLUTION: [18, -768, -364, 32760, 5120, 0, 3840]

PROBLEM: [[-15, -3, 8], [13, -41, -38, 19, 43], [-28, 6], [12, 18, 41, -9], [37, -29], [-45, -16], [19, -38, 1, 43], [25, 28, 40, 50], [5, -47, -11, 40, -50], [-26, -49], [-40, -42, -7], [-8, 9, 32, 47]]

SOLUTION:
[8, -38, -168, 216, 0, -16, -38, 56000, -2000, -26, 1680, -256]
