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: [[26, 22, -22, -41], [-27, -30, 35, -49], [44, 10], [30, 5, -47, 37], [25, -15, 48], [-42, -21], [41, -48], [19, 18, -10, -4]]

SOLUTION: [-12584, -30, 440, 30, 48, -42, -48, 720]

PROBLEM: [[-19, 28, -49, -21], [-16, 20], [-26, -46, 4, -39], [-12, 12, 40, -21, -4], [43, -20, -28], [17, -11, 24, 40, 7], [-42, -4], [-48, 15, 10], [-48, -50, 2, 6, -39], [6, -8], [-23, 45], [-27, -41, -40, 30]]

SOLUTION: [28, -320, 4784, 23040, 560, 960, 168, -480, 28800, -48, 0, -1200]

PROBLEM: [[28, 46, 15], [21, -49], [14, 48, 2, -25], [-8, 38], [-32, 0, -42], [-23, -31, -4, -12, -33], [-20, -46, -32], [-32, 32], [-15, -1, 30], [43, -3, -47], [26, 38, -44, -32], [25, 42], [-41, -7, 20], [-8, 5, 29, -17, 20], [44, 12, -46, 5, -31]]

SOLUTION:
[1288, 0, 1344, -304, 0, 48, -29440, -1024, 30, 0, 1391104, 42, 20, -160, -24288]
