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: [[-2, 16, -17], [34, -41, 9, 38], [-14, 13, -40, -3]]

SOLUTION: [-32, 1292, 560]

PROBLEM: [[48, -4, -48, 25], [-20, 1, -44, -29], [-38, -30, 41, -3, 29], [36, -36, -30], [-42, 33], [34, -32], [-15, 14], [-8, 41, 30, 29, 43], [22, -32, -18, -1, -47], [-26, 48], [-34, -12, 5], [-4, -25, -48], [-42, -22], [-15, 22, -7, 3], [7, -29]]

SOLUTION:
[9216, 880, 1140, 38880, -42, -1088, 14, -240, 12672, -1248, 408, 192, 924, 22, 0]
