Your program was decomposed into 6 terminating modules (3 trivial, 2 deterministic, 1 nondeterministic). One deterministic module has affine ranking function null and consists of 4 locations. One deterministic module has affine ranking function null and consists of 4 locations. One nondeterministic module has affine ranking function null and consists of 4 locations. 3 modules have a trivial ranking function, the largest among these consists of 16 locations.
