Your program was decomposed into 6 terminating modules (2 trivial, 4 deterministic, 0 nondeterministic). One deterministic module has affine ranking function null and consists of 4 locations. One deterministic module has affine ranking function (length2 + ((long long) -1 * i)) and consists of 4 locations. One deterministic module has affine ranking function null and consists of 10 locations. One deterministic module has affine ranking function null and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 14 locations.
