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: [[23, 12, 35, -33], [6, -37, -14, 23], [-25, -14], [12, -50, 11, -38, 36]]

SOLUTION: [12, -84, -14, 820800]

PROBLEM: [[-2, -30], [26, -22, -44, -2], [16, 28], [38, 39, 16, 14], [-18, -49, 35, -16, -18], [31, 23, 2, -3], [3, 49], [31, 22], [-1, -5, -44], [-35, -41, 23], [-14, -11, -44], [10, 18], [25, 1, 37], [-36, -45, 16]]

SOLUTION: [60, -50336, 448, 8512, -5184, 2, 0, 22, -44, 0, 616, 180, 0, -576]

PROBLEM: [[7, 45, -7], [37, -10], [-1, -15], [25, -8, -9, 26], [5, -18, -24, 17, 25], [-39, -49, -19, 19, 21], [-14, -6, -25, -24], [-32, 19, -40], [33, 3], [-16, 46, 37, -21, 30], [7, -48, 50, -46], [-43, -39, 16, 2, -29]]

SOLUTION:
[0, -10, 0, -208, 432, 0, -2016, 1280, 0, -22080, 110400, 32]
