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, 46], [1, -11], [-10, 6, -11], [-32, -37, -50, 31]]

SOLUTION: [2116, 0, -60, 1600]

PROBLEM: [[-24, 17], [17, -5, -26, 42], [4, -1, 4, -21], [-28, -19, -18, -15, -47], [11, 31], [49, -7], [37, 4, 48, 47, -13], [21, 48], [-46, -27, -24], [-4, 19, 10, 44, -12]]

SOLUTION: [-24, -1092, 16, 504, 0, 0, 192, 48, 1104, 21120]

PROBLEM: [[-27, 30, -19], [-34, -9, -37, -10, -43], [-15, -44], [22, 12, 21], [-29, -6, 32, 23], [-23, 33, -26, 27], [11, -4], [-20, 2, 28, -14, 44]]
