  - StatisticsResult: Constructed decomposition of program
    Your program was decomposed into 8 terminating modules (3 trivial, 4 deterministic, 1 nondeterministic). One deterministic module has affine ranking function (length1 + ((long long) -1 * i)) and consists of 2 locations. One deterministic module has affine ranking function null and consists of 3 locations. One deterministic module has affine ranking function null and consists of 5 locations. One deterministic module has affine ranking function null and consists of 5 locations. One nondeterministic module has affine ranking function null and consists of 4 locations. 3 modules have a trivial ranking function, the largest among these consists of 29 locations.
