- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 5 terminating modules (2 trivial, 3 deterministic, 0 nondeterministic). One deterministic module has affine ranking function (length1 + ((long) -1 * i)) and consists of 4 locations. One deterministic module has affine ranking function (length2 + ((long) -1 * i)) and consists of 4 locations. One deterministic module has affine ranking function null and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 20 locations.
