以前、境界条件を含んだランダムウォークについて質問させていただきました。python３でかいてあったので、今回はこれをJuliaで書き直しましたが、エラーなしで動くのですが、結果がおかしく、pythonと全く同じように書いてあるはずなのですが、間違えがわかりません。

```

        stage[:,:,1]=[1 1 1;1 0 1;1 1 1]
        stage[:,:,2]=[1 0 1;0 0 0;1 0 1]
        stage[:,:,3]=[1 1 1;1 0 1;1 1 1]
        #println(walk)
        for itr in 1:10
            walk = zeros(Int8,n,n,n)
            walk[1,1,1]=1
            for t in 0:10

        end
        println("t=0:",count0,"\n","t=6:",count1,"\n","t=36:",count2,"\n","t=216:",count3,"\n","t=1296:",count4,"\n","t=7776:",count5,"\n","t=46656:",count6,"\n")
    end
    main()
    
```

ランダムウォークの再帰性ができているか、t=0で今回はcount0=10になるはずなのですが、０になったままで、すこしおかしいのですが、どこが間違っているのでしょうか、、、。  
結果（乱数なので一例）  
t=0:0  
t=6:3  
t=36:0  
t=216:0  
t=1296:0  
t=7776:0  
t=46656:0  
宜しくお願い致します。わかり次第自分も報告します。
