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: [[20, -8, -15, -38, 13], [24, 40, -45, -20, 49], [-32, -38, -46, -16], [38, 50, -15], [-29, 36, 14], [-47, 0], [48, -3, -24, -6], [19, -17, 31], [25, 43, 30, -30], [41, -4, -45], [-35, 11, 30, 26, 38], [5, 35]]

SOLUTION: [6080, -19200, 894976, 1900, 504, 0, 6912, 0, -900, -4, 29640, 0]

PROBLEM: [[35, 17, 7, -41, 22], [33, -17], [-50, 31]]

SOLUTION: [22, 0, -50]

PROBLEM: [[-35, 3, 39, 35], [30, -12, 38, 20, -24], [28, -2], [1, 46, -21, 24, -9], [33, -29, 37, 43], [40, 11, 33], [41, -21, 48, 44, -22], [37, 48, 46, 0], [-40, -18, 28, -11, -10], [34, -12, -34, -3], [15, 50, 34, -16, -12], [36, 13, 27, -16, -33], [32, -28, -50], [49, 48, 43]]

SOLUTION:
[0, 6566400, -56, 1104, 0, 40, -46464, 0, -201600, 13872, 326400, -576, 44800, 48]
