Til a breyta r prefix yfir infix mtti nota sr forriti bls. 206 (eins og kom fram ur) og sta ess
a hafa t.d. "return eval() + eval();" myndi maur kalla eval(), prenta san t "+" og svo kalla aftur eval().
egar tala er fundin er hn prentu t ( sta ess a skila henni me "return x;").

Yfirleitt er ekki hgt a ba til einkvmt tr r inorder r hnta ess. a geta veri mrg mismunandi tr me
smu inorder r. Hins vegar egar um er a ra segatr (expression trees) er komi skilyri tr, sem segir a
innri hntar eru virkjar (+, -, *, /, ...) og laufin eru tlur ea breytur. vri hgt a nota svipaa afer og
notu er forritinu bls. 152 til a ba til segatr sta ess a ba til postfix seg.
