Mathespiel - Bruter :)

Also vielleicht kann jemand das Prog irgendwann für Knobelaufgaben im Mathe Unterricht gebauchen :D

Ich war zufaul alle Zahlen durch zutesten
...Aufgabe war 3x3 KästienQuadrat
Jede senkechte und waagerechte Reihe muss 15 ergeben
und es dürfen dort keine Zahlen doppelt vorkommen.

Code:

---

/*
    ##########
    #a1#b1#c1# = 15
    ##########
    #a2#b2#c2# = 15
    ##########
    #a3#b3#c3# = 15
    ##########
    15  15  15
*/
