- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 11 terminating modules (6 trivial, 4 deterministic, 1 nondeterministic). One deterministic module has affine ranking function length1 + -1 * i and consists of 5 locations. One deterministic module has affine ranking function length2 + -1 * i and consists of 4 locations. One deterministic module has affine ranking function -1 * s1 + length1 and consists of 4 locations. One deterministic module has affine ranking function unknown-#length-unknown[nondetString2] + -1 * scanp and consists of 4 locations. One nondeterministic module has affine ranking function unknown-#length-unknown[nondetString2] + -1 * scanp and consists of 4 locations. 6 modules have a trivial ranking function, the largest among these consists of 27 locations.
