Befunge er tvívítt, hlaðabundið, sjálfbreytandi forritunarmál, lýst sem blöndu milli Forth og Lemmings. Chris Pressey bjó það til árið 1993. Befunge forrit er skrifað á 25×80 hjólflötung af bókstöfum, flæðisstjórn forritsins er ákvörðuð útfrá því að fylgja örvatáknum. Það er einn hlaði heiltalna, afhlöðun af tómum stafla skilar heiltölunni 0.

Skipanirnar eru:

Tölustafur

09

Hlaðið þessarri (eins stafa) tölu ofan á hlaðann.

Tvístæð aðgerð

+-*/%

Afhlaðið a og b, hlaðið síðan ba.

Neitun

!

Afhlaðið a. Ef a=0 hlaðið 1 annars 0.

Meira en

Afhlaðið a og b. Ef b>a hlaðið 1 annars 0.

Örvar

<>^v

Breytið stefnu í vinstri, hægri, upp, niður.

Lárétt val

_

Afhlaðið a; setjið stefnu til hægri ef a=0, annars vinstri.

Lóðrett val

|

Afhlaðið a; setjið stefnu niður á við ef a=0, annars upp á við.

Strengjastilling

"

Hlaðið ASCII gildum eftirfarandi stafa á hlaðann þar til rekist er á "

Afritun

:

Afhlaðið a, hlaðið a tvisvar.

Skrá

p

Afhlaðið r, c, og v. Setjið v í röð r, dálk c.

Sækja

g

Afhlaðið r og c. Hlaðið gildinu í röð r, dálk c.

Víxlun

\

Víxlið efstu tveimur gildum hlaðans.

Henda

$

Afhlaðið (og hendið gildinu.)

Prenta tölu

.

Afhlaðið a og prentið a sem heiltölu með bili á eftir.

Prenta staf

,

Afhlaðið a og prentið a-ta ASCII stafinn.

Brú

#

Hunsið næsta reit.

Hætta

@

Ljúkið keyrslu.

Ekkert

 

(Bil.) Gerir ekkert.

Forritið byrjar á vinstrasta staf fyrstu línu og stefnir til hægri.

Fyrir b/a og b%a má gera ráð fyrir að b0 og a>0. Deiling er heiltöludeiling, rúnnuð niður á við. Fyrir aðgerðirnar skrá og sækja má gera ráð fyrir að 0r24 og 0c79. Engin reikniaðgerð skilar tölu utan bilsins 2147483648 til 2147483647. Sérhver stafur sem , skilar er prentanlegur ASCII stafur á bilinu 20126 eða nýlínustafur með ASCII gildi 10. Gefið er að forritið muni keyra mest 1000000 skref og prentar að minnsta kosti einn staf sem er ekki bilstafur.

Input

  • Ein lína með tölunni n{1,,25}, fjöldi Befunge kóðalína.

  • n línur Befunge kóða, hver samanstandandi af 80 stöfum.

Output
