  - StatisticsResult: Constructed decomposition of program
    Your program was decomposed into 10 terminating modules (5 trivial, 3 deterministic, 2 nondeterministic). One deterministic module has affine ranking function (((long long) -2 * a) + 11) and consists of 3 locations. One deterministic module has affine ranking function (((long long) -2 * b) + 11) and consists of 4 locations. One deterministic module has affine ranking function (((long long) -2 * c) + 11) and consists of 3 locations. One nondeterministic module has affine ranking function (((long long) -2 * c) + 11) and consists of 3 locations. One nondeterministic module has affine ranking function (((long long) -2 * b) + 11) and consists of 4 locations. 5 modules have a trivial ranking function, the largest among these consists of 10 locations.
