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: [[19, 43, 37, 28], [47, 1, 11, 14, 41], [25, -9, -37, 49, 4], [-35, 20, 8], [41, -20], [8, -31, -17, 1], [36, -38], [-19, 35, 6, 17], [1, -13]]

SOLUTION: [28, 14, 4, 160, -20, 8, -1368, 6, 0]

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]]
