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: [[24, -25, 11], [36, -21, -33, -17, 27], [41, -45, -1, -50], [40, -31, 20, -13, -45], [47, 7], [-21, 0, 22], [21, -16, 21, 33, 5]]

SOLUTION: [24, 36, -50, 800, 0, 0, -16]

PROBLEM: [[-18, 29, 9, 11], [-1, -10, 33, -16], [-13, 37, 1, 20], [27, -42, -14, 3], [-11, 35, -2], [-23, -36], [14, 47]]

SOLUTION: [-18, 160, 20, 588, -2, -36, 14]

PROBLEM: [[21, -41, 7], [44, 19, 6, -2], [6, 35, -48, -49, 28], [-14, -5, -38, 16]]

SOLUTION:
[0, -528, -8064, 8512]
