  - StatisticsResult: Constructed decomposition of program
    Your program was decomposed into 2 terminating modules (0 trivial, 2 deterministic, 0 nondeterministic). One deterministic module has affine ranking function (199 + ((long) -2 * y)) and consists of 3 locations. One deterministic module has affine ranking function (((long) -2 * z) + 199) and consists of 2 locations.
