- 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 unknown-#memory_int-unknown[x_ref][x_ref] and consists of 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 3 locations.
