- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 8 terminating modules (4 trivial, 4 deterministic, 0 nondeterministic) and one nonterminating remainder module.One deterministic module has affine ranking function a20 and consists of 4 locations. One deterministic module has affine ranking function a8 and consists of 4 locations. One deterministic module has affine ranking function a17 and consists of 4 locations. One deterministic module has affine ranking function a7 and consists of 3 locations. 4 modules have a trivial ranking function, the largest among these consists of 10 locations. The remainder module has 17182 locations.
