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: [[-10, -29, 46, -26], [-19, 20, -25, -39, 41], [0, -14, 7], [-15, -45, -50, 6], [45, -19, 25], [46, 40, -14, 44, -43], [-42, 50, 47, -37], [-1, -37, -35], [40, -18, -2, 5], [11, -4, -2, 26, -4], [27, -46, 15], [0, 24, -8, 41], [-3, -17], [13, 45, 24]]

SOLUTION: [11960, 20, 0, -300, 0, -1133440, -2100, 0, 1440, -832, -46, 0, 0, 24]
