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: [[-36, 13, 37, -31], [-3, -10], [18, 17, 36], [-11, 35, 27, 30, 37], [4, 8], [31, 38, -26], [-29, 5], [9, 14, 37, -17], [28, 47, 24, -20, -21], [21, -13]]

SOLUTION: [-36, -10, 648, 30, 32, -988, 0, 14, -13440, 0]

PROBLEM: [[-23, -22], [7, -46], [-5, -1, -49, -1], [15, -6], [-39, -42, -25, -4], [-2, 1, -40], [-33, -29, -18, 33, 48], [-5, -12, 44, -38, 9], [-50, -49, 44, -37, 47]]

SOLUTION: [-22, -46, 0, -6, 168, 80, -864, 20064, -2200]

PROBLEM: [[-1, -9], [-18, 32, -7, 23], [42, -20, 47, -2], [48, -32, 6, 24, -30], [33, -8, -22], [1, 16], [-39, -3, -39, -45, 43], [-32, 30, 6, 49, -18], [44, -43, -24, -28], [35, -29, 33, 47], [-15, -37, -40, -18], [3, -38, -45, -36], [23, 5, 43, 43, -42]]

SOLUTION:
[0, -576, 1680, 6635520, 176, 16, 0, 103680, 29568, 0, 720, 1368, -42]
