Solve the following python programming problem given the following code:
def test_spatiotemporal_cubes() : 
    def check_patch_coverage(files) : 
        rng = numpy.random.RandomState (1) 
        inputs = [(name, array.shape) for (name, array) in six.iteritems (files)] 
        shape = (5, 7, 7) 
        for (fname, index) in spatiotemporal_cubes (inputs, shape, 50000, rng) : 
            cube = files [fname] [index] 
            if (len (files [fname].shape) == 3) : 
                assert (cube.shape == shape) 
else : 
                assert (cube.shape [: 3] == shape [: 3]) 
cube [...] = True 
for (fname, array) in six.iteritems (files) : 
            assert array.all () 
files = OrderedDict (file1 = numpy.zeros ((10, 30, 21), dtype = bool), file2 = numpy.zeros ((15, 25, 28), dtype = bool), file3 = numpy.zeros ((7, 18, 22), dtype = bool)) 
    check_patch_coverage (check_patch_coverage) 
    files = OrderedDict (file1 = numpy.zeros ((10, 30, 21, 3), dtype = bool), file2 = numpy.zeros ((15, 25, 28, 3), dtype = bool), file3 = numpy.zeros ((7, 18, 22, 3), dtype = bool)) 
    check_patch_coverage (files)
