- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 6 terminating modules (3 trivial, 3 deterministic, 0 nondeterministic) and one nonterminating remainder module.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 deterministic module has affine ranking function null and consists of 3 locations. 3 modules have a trivial ranking function, the largest among these consists of 14 locations. The remainder module has 39 locations.
