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: [[-29, 37, -20], [13, 17, 13, -33, 2], [-8, 34, -44]]

SOLUTION: [-20, 2, 11968]

PROBLEM: [[35, 43], [-37, -27, -27, -21, -45], [-38, 42, -48, 12], [-9, -47, -44, -36], [14, -2], [-31, -30, 49, -6], [-26, 42], [-13, 32, 14, -31, 21], [37, -7, 2, -45, -33], [-42, -21, 1, 27, -20], [-36, -19], [42, -10, 50, -16, 22], [17, 23, 23], [-10, 4, -13], [38, 13, -22, 5, -50]]

SOLUTION: [0, 0, 919296, 1584, -28, 180, -1092, 448, 2, 840, -36, 7392000, 0, -40, 41800]

PROBLEM: [[-25, 43], [-3, 49, -29], [-45, 44, -19, -3], [27, 49, -30, -29], [23, -26, 41], [-34, -23, -34, 30, 6], [-31, 10, 31, -6], [15, 14, 5, -14, 20], [34, -46], [14, 33], [10, -7, -12], [-11, 27, 19, -6, 20], [-11, -24, -21], [-9, 49, -32, 41, -21], [20, -10, 25, 38]]

SOLUTION:
[0, 0, 44, -30, -26, 208080, -60, -3920, -1564, 14, -120, -120, -24, -32, -7600]
