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: [[-20, -9, -4, -22], [-9, 29], [-41, -3, 12], [-26, 35, 7], [-22, -28, 50, -42, -49], [9, -3, 20, 5, -3], [41, -49, 44, 35, 27], [10, -46, -48], [32, -21], [47, -15, 28, -13]]

SOLUTION: [-1760, 0, 12, -26, -1293600, 20, 44, 22080, 32, 28]

PROBLEM: [[38, 28], [-17, 24], [0, -7, -15, -8]]

SOLUTION: [1064, 24, 0]

PROBLEM: [[25, 46, 0, 2, -46], [46, -41, 9, -23, -11], [46, -25], [46, 26, -22, -28], [36, 34, -48, 5], [24, 44], [44, -39, -22, 36, -33], [-19, 32], [12, -28, 11, -36, 16], [-47, -2, 12, 24, 34], [28, -10, -12, 23], [-12, -43, -6, 47], [45, 35, 33, 46], [34, 32, -35, -34, -6], [20, 40, 8, -10]]

SOLUTION:
[0, 46, 46, 736736, -58752, 1056, -34848, 32, 193536, -19584, 3360, 72, 46, 221952, -64000]
