- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 7 terminating modules (3 trivial, 3 deterministic, 1 nondeterministic). One deterministic module has affine ranking function (((long long) -2 * i) + 201) and consists of 5 locations. One deterministic module has affine ranking function ((((long long) -2 * i) + ((long long) -2 * j)) + 39) and consists of 5 locations. One deterministic module has affine ranking function (7 + ((long long) -2 * k)) and consists of 4 locations. One nondeterministic module has affine ranking function (7 + ((long long) -2 * k)) and consists of 4 locations. 3 modules have a trivial ranking function, the largest among these consists of 16 locations.
