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: [[-15, 35, 29], [-7, -17, 19], [-40, -37, -1, 47, -29], [-26, -3], [-16, -28, -13, -19], [38, -44], [-20, -14, 49, 44], [-33, -10, -37], [-11, 11, 26, 48], [-18, 32, 49], [-19, -36, -3, -45, 7]]

SOLUTION: [0, 0, -40, -26, 448, -1672, 12320, -10, 1248, -576, -36]

PROBLEM: [[23, -48, -18], [9, 47, 33, 32, -22], [-30, -23, 9, -25, -17], [-39, 8, 27], [3, -34, 8, -42]]

SOLUTION: [864, -704, -30, 8, 11424]

PROBLEM: [[25, 33, -23, -44, 7], [-20, 33], [27, -9, -28, -40], [-5, 34, -30], [-22, -20, 41, 9], [-28, -39, -24, 47, -32], [16, 16, -39, 34], [-25, 23, 28, 15], [24, 46, 39, -17, 24], [-37, 10, 1, -19], [2, 45, -42], [-6, 17, 1, 50, 17]]

SOLUTION:
[-44, -20, 1120, -1020, 440, -21504, 8704, 28, 26496, 10, -84, -300]
