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: [[46, 20, -17, 40, -35], [17, -45, 39, 43, -42], [12, -9], [18, 21, -29], [-27, -8, -18, -21, 15], [9, -33, -30, 21, 8], [-15, 39, 8], [-17, 13, -37, -10], [9, -33], [2, 10, 23, 41, 47], [17, 5, 6, -21, 16], [-44, -8]]

SOLUTION: [36800, -42, 12, 18, 144, -240, 8, -10, 0, 20, 96, 352]

PROBLEM: [[-38, 48, 1], [-4, -35], [28, 26], [34, 38, -46, 23], [-3, -47, -1, 32, -41]]

SOLUTION: [-1824, -4, 728, -59432, 32]

PROBLEM: [[-9, -38, 36, 16, 25], [-15, 18, 50, 6, -14], [-36, -48, -12], [38, 17], [-11, 15], [6, -21], [-47, -29, -47], [-45, 27, 50, 7, 38], [-37, 24, 0], [41, 29, 31, 49, -16], [-49, -3, -46, -10], [-24, 27, 15, -17], [-22, 5, -42], [-11, -22, 20]]
