  - StatisticsResult: Constructed decomposition of program
    Your program was decomposed into 2 terminating modules (1 trivial, 1 deterministic, 0 nondeterministic). One deterministic module has affine ranking function ((-2 * splverifierCounter) + 7) and consists of 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 3 locations.
  - StatisticsResult: Timing statistics
