- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 11 terminating modules (8 trivial, 3 deterministic, 0 nondeterministic). One deterministic module has affine ranking function -1 * str + unknown-#length-unknown[str] + -1 * i and consists of 4 locations. One deterministic module has affine ranking function -1 * str + unknown-#length-unknown[A] + -1 * start and consists of 5 locations. One deterministic module has affine ranking function j and consists of 6 locations. 8 modules have a trivial ranking function, the largest among these consists of 10 locations.
