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: [[-6, 2, 2, 46, 47], [36, 22, 9], [-21, -44], [-39, -3, 45, -41], [-19, -36, -40, 2], [-18, 7, 6], [30, 17], [49, 50, 22], [-12, 22, 41, 42, 3], [-38, -7, -48], [-41, -36], [23, -29, -16, 21], [-26, -6, -37, 23], [-3, 0, 14]]

SOLUTION: [-1104, 792, -44, 0, 2880, -108, 30, 1100, -11088, 1824, -36, -16, 156, 0]

PROBLEM: [[23, 12], [7, -46, 34, -2, 22], [-20, 12, -45, 15, 6], [30, -4, 50, -26, -39], [26, 43, -22, 34, -29]]

SOLUTION: [12, 68816, -1440, 156000, -19448]

PROBLEM: [[-43, -18], [-19, -17, -5], [-20, -21], [14, -35, 8, -36, -10], [12, -45, -40, -9], [-32, -15, 37, -20, -4], [25, -14], [5, 27, -30, 8], [-1, 36, 36, 25, -24], [29, 42], [-26, -50, -50, -20, 10], [22, 47, 2, 50]]

SOLUTION:
[-18, 0, -20, 40320, -480, -2560, -14, -240, -31104, 42, 13000000, 2200]
