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, 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: [[-12, -42, -47, -30], [37, 29, -20, 46, -7], [-17, -43], [-16, -26, -5], [-18, 10], [-43, 26], [1, 23], [-22, 34, -4, -21], [-37, 25]]

SOLUTION: [-15120, -920, 0, 416, -180, 26, 0, 2992, 0]

PROBLEM: [[-45, 21, 13], [-36, 11, 47, 41, 31], [-22, 5], [-42, 15, 36, 25], [-34, 23], [-41, 15, -47], [-3, 32, -18, 25, 27]]

SOLUTION:
[0, -36, -22, -1512, -34, 0, -576]
