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: [[-11, -13, 7, 45, 46], [-5, -20], [6, -15, -6, 17, 26], [46, 26, -25, -47], [-18, -12], [30, -22], [4, 32], [-43, -26], [6, 4, -2, -32], [21, -26, -36, 41], [-14, 24, -31], [20, -16, -15, -50], [50, 30, 5, 46], [-25, -15]]
