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: [[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]

PROBLEM: [[17, -18, 9], [-42, -12], [39, -2, 31, 14], [-16, -9, -20], [19, -30], [47, -29, -40]]

SOLUTION: [-18, 504, -28, 320, -30, -40]

PROBLEM: [[-11, -23, 30], [-42, -13, 34], [16, 20], [6, 26, 6, 3, -14], [37, 42, -37, 15], [-27, 39, 3, 40], [9, -35], [-27, 21, 50, 14], [21, -28], [-4, -45, -14], [-1, -20, -10, -24, 10], [-39, 20, -22], [-3, -44, -31, -23], [17, -12], [-38, -36, -29]]

SOLUTION:
[30, -1428, 320, -13104, 42, 40, 0, 700, -28, 56, -48000, -440, -44, -12, 1368]
