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: [[41, 32], [17, -11, -29, 21, 34], [21, 31, 11], [39, -49, 17, -39, 11], [30, 3, -50], [31, -3, 6, 29]]

SOLUTION: [32, 34, 0, 0, -1500, 6]

PROBLEM: [[-35, 39], [-23, -1, -39], [-29, -23], [47, -4, -6], [-27, -50, 39, -35], [44, -33, 40, -48], [-10, 23, 40, -30], [-3, -48]]

SOLUTION: [0, 0, 0, 24, -50, -84480, 12000, -48]

PROBLEM: [[26, -26, -33, -5, -38], [-17, 34, 34, -14, 30], [47, 35], [-33, -2], [24, -2, -12], [-42, 26, 40, -25], [44, -18, -9, -47], [-29, -11, 42, -12], [43, -12], [-1, 31]]

SOLUTION:
[25688, -485520, 0, -2, 576, -43680, -792, -504, -12, 0]
