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: [[-37, -20, 18, -43, 7], [-49, -13, 11], [-29, -31], [-9, 6, -6], [3, 44, 33, -15, 20], [31, 20, 4, 49, -22]]

SOLUTION: [-360, 0, 0, -36, 880, -1760]

PROBLEM: [[-10, -10, 47, 28], [-27, 0, 24], [-5, 38, -39], [-37, -15, 16, 9, -37], [23, -2], [-42, 6, 0], [7, 24, -48, 22], [5, -46], [-35, 0, -49, 21], [-5, -35, -22, -38, -7], [-10, -2, 30, 44, 3], [20, 9, 30, -34], [31, 6, 42, 26, -24]]

SOLUTION: [2800, 0, 38, 16, -2, 0, -25344, -46, 0, 836, 26400, -20400, -157248]

PROBLEM: [[44, 35, -30, -9], [-2, -18], [-23, -15, 40], [15, -48, -29, -35, 0], [-20, -23], [48, 50, -30, -26], [-50, -11, -15], [-40, -10, 11, -22, 33], [36, 40, 12, -15, -23], [28, 29, 47, -4], [9, 47, -47, -32], [10, -30, 20, -7], [-21, -33, -9], [-2, -1, 30, -19, 20]]

SOLUTION:
[-1320, 36, 40, 0, -20, 1872000, -50, -8800, 17280, -112, -32, -6000, 0, -1200]
