Proof step 29 from proof getintarray-in (previous step)

∃ j. i = st[r -- j '] .intval ∧ ¬ j < 0 ∧ ¬ st[r -- _length] .intval ≤ j ⊦ ∃ n. n < # getarray(r, 0, st[r -- _length] .intval, st) ∧ (intvalues(getarray(r, 0, st[r -- _length] .intval, st))[n]) = i

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 19:
⊦ 0 < j → # getarray(r, i, j, st) = i→n(j)
Proof step 28:
0 < st[r -- _length] .intval, 0 ≤ j, j < st[r -- _length] .intval ⊦ ∃ n. ¬ i→n(st[r -- _length] .intval) ≤ n ∧ (intvalues(getarray(r, 0, st[r -- _length] .intval, st))[n]) = st[r -- j '] .intval
