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: [[8, 27], [47, -6, -15, 5, 47], [-16, -48, 0, 37, -44], [-21, -20, 13, -47], [-38, -47], [-33, -19, 44, 24, 9], [47, -15], [-20, 5, -13, -18], [32, -27, 21, -34, 3], [-49, 38, 25]]

SOLUTION: [8, -6, 0, -20, -38, 1056, 0, 360, -1088, 38]

PROBLEM: [[7, -39, -8, -38, -50], [29, -39, -35, -40], [13, 2, -36, -37, -32], [12, -29, -22, 26], [-48, 35, -3], [4, 38, -42, 10]]

SOLUTION: [-15200, -40, 2304, -6864, -48, -63840]

PROBLEM: [[-22, 23, 33], [20, -46, -21], [2, -23, 17, -6, -21], [4, 20, -21, 44, 43]]

SOLUTION:
[-22, -920, -12, 3520]
