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: [[1, 50, -3], [7, 23, 15], [-3, 12, 4, -22, -34], [-13, 48], [16, -41, -37, 43, 41], [-24, 13, 28, 8], [-30, -2, 12], [-1, 13, -50], [49, 11, -11, -34], [-15, 5, 8], [-26, 21]]

SOLUTION: [50, 0, 35904, 48, 16, -5376, 720, -50, -34, 8, -26]

PROBLEM: [[-15, -10, -49, -8], [-49, -13], [-35, 9, -26, 50], [-43, -50, 9, -43, 20], [-30, -41], [-40, 42, -20, 31, 50], [-50, 1, -31], [42, -33, -14, 25, 47], [-45, -39], [29, 13, 27, -49], [18, 46], [-27, -50, -24], [-32, 39, -13], [-1, 10, 41, 25, -26]]

SOLUTION: [80, 0, -1300, -1000, -30, 1680000, -50, -588, 0, 0, 828, 1200, -32, -260]

PROBLEM: [[23, 13, 39, 3], [39, -1, -11], [36, 19, -44, 33, 28], [12, -39, 37, -48], [29, -25, 0], [18, -14, 23, 29, -8], [-20, 25], [13, 16], [25, 11, -7], [19, -36, 28], [7, -14, -48], [-46, -45, 22, 4], [22, -6, -33]]

SOLUTION:
[0, 0, -44352, -576, 0, 2016, -20, 16, 0, -1008, 672, -4048, -132]
