  - StatisticsResult: Constructed decomposition of program
    Your program was decomposed into 7 terminating modules (4 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 5 locations. One nondeterministic module has affine ranking function null and consists of 6 locations. 4 modules have a trivial ranking function, the largest among these consists of 20 locations.
