- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 3 terminating modules (0 trivial, 3 deterministic, 0 nondeterministic). One deterministic module has affine ranking function v and consists of 6 locations. One deterministic module has affine ranking function null and consists of 6 locations. One deterministic module has affine ranking function ((2 * v) + 4294967295) and consists of 5 locations.
