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, -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: [[-46, -13], [35, 15, 47], [-7, 36, 35], [41, -2], [26, 14, 35], [-47, -27, -29, 44], [16, -49, -11, 9], [37, 19, 48, -17]]

SOLUTION: [-46, 0, 36, -2, 364, 44, 16, 48]

PROBLEM: [[-48, -50, -33], [-43, 36, -34, 15, -7], [11, -21, -3, 46, 10], [15, -11, 23], [43, -41, -12, 43, 19], [-26, 25, -6, 24, -22], [-6, 13, 37, -14], [-12, 19, -19, 38, -1], [-21, -17]]

SOLUTION:
[2400, -1224, 460, 0, -12, -82368, 84, -456, 0]
