- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 4 terminating modules (0 trivial, 3 deterministic, 1 nondeterministic). One deterministic module has affine ranking function (199 + ((long long) -2 * x)) and consists of 4 locations. One deterministic module has affine ranking function (199 + ((long long) -2 * x)) and consists of 4 locations. One deterministic module has affine ranking function z and consists of 4 locations. One nondeterministic module has affine ranking function (199 + ((long long) -2 * x)) and consists of 4 locations.
