One deterministic module has affine ranking function array_size + -1 * i and consists of 5 locations. One deterministic module has affine ranking function -1 * pass + n and consists of 3 locations. One deterministic module has affine ranking function 1073741823 * pass + -1 * i and consists of 6 locations. One nondeterministic module has affine ranking function -4 * i + 8589934570 + -1 * numbers and consists of 10 locations.
