- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 2 terminating modules (2 trivial, 0 deterministic, 0 nondeterministic) and one nonterminating remainder module.2 modules have a trivial ranking function, the largest among these consists of 6 locations. The remainder module has 186 locations.
