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: [[7, 12, -50, 24], [-25, 29, 2, 42, -1], [-17, -33, 28], [-43, -46], [24, 19, 11, -27], [7, 13, -39, 18], [-19, -50, -21]]

SOLUTION: [-14400, 84, 28, -46, 24, 18, -50]

PROBLEM: [[-6, 2, 2, 46, 47], [36, 22, 9], [-21, -44], [-39, -3, 45, -41], [-19, -36, -40, 2], [-18, 7, 6], [30, 17], [49, 50, 22], [-12, 22, 41, 42, 3], [-38, -7, -48], [-41, -36], [23, -29, -16, 21], [-26, -6, -37, 23], [-3, 0, 14]]

SOLUTION: [-1104, 792, -44, 0, 2880, -108, 30, 1100, -11088, 1824, -36, -16, 156, 0]

PROBLEM: [[-5, 30, -4, 25], [2, -7], [45, -31, -16], [21, -23], [-43, 46], [-24, 44, 33, -28], [8, 0, -14, 4, -2], [-13, 40, 23, -17, 40], [-28, 19, 25, 38], [18, -16, -32, -47]]

SOLUTION:
[-120, 2, -16, 0, 46, 29568, 0, 1600, -1064, 9216]
