- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 5 terminating modules (2 trivial, 2 deterministic, 1 nondeterministic). One deterministic module has affine ranking function (n + (-1 * k)) and consists of 3 locations. One deterministic module has affine ranking function ((-1 * i) + n) and consists of 4 locations. One nondeterministic module has affine ranking function ((-1 * i) + n) and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 5 locations.
