- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 2 terminating modules (1 trivial, 1 deterministic, 0 nondeterministic). One deterministic module has affine ranking function (((long long) -2 * splverifierCounter) + 7) and consists of 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations.
