- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 7 terminating modules (4 trivial, 3 deterministic, 0 nondeterministic) and one nonterminating remainder module.One deterministic module has affine ranking function (((long) -1 * i) + length) and consists of 4 locations. One deterministic module has affine ranking function (((long) -1 * j) + length) and consists of 3 locations. One deterministic module has affine ranking function (((long) -1 * j) + length) and consists of 3 locations. 4 modules have a trivial ranking function, the largest among these consists of 21 locations. The remainder module has 33 locations.
