Das ist wohl der Einfachste:
Code:
[color=olive]1[/color]
4 2 4 [color=olive]9[/color] 2
[color=olive]7[/color] 5 [color=olive]3[/color] [color=olive]3[/color] 5 [color=olive]7[/color] = 15
8 6 8 [color=olive]1[/color] 6
[color=olive]9[/color]
[color=olive]1[/color]
[color=olive]6[/color] [color=olive]2[/color]
11 7 3 11 [color=olive]24[/color] 7 [color=olive]20[/color] 3
[color=olive]16[/color] 12 8 [color=olive]4[/color] [color=olive]4[/color] 12 [color=olive]25[/color] 8 [color=olive]16[/color]
[color=olive]21[/color] 17 13 9 [color=olive]5[/color] 17 [color=olive]5[/color] 13 [color=olive]21[/color] 9 = 65
[color=olive]22[/color] 18 14 [color=olive]10[/color] [color=olive]10[/color] 18 [color=olive]1[/color] 14 [color=olive]22[/color]
23 19 15 23 [color=olive]6[/color] 19 [color=olive]2[/color] 15
[color=olive]24[/color] [color=olive]20[/color]
[color=olive]25[/color]
Der Code wdürfte ja nicht so schwer sein, einfach alles, was aus dem Quadrat herausragt, um eine Quadratlänge ins Quadrat hineinschieben...
