Given the following C code and unoptimized assembly code, your task is to generate highly optimized x86-64 assembly code.
C Code:

```c
W=87,i,n;char a[100002],s[100002];f(x,y){*a=x;a[1]=y;for(i=0;++i<=n;)a[i+1]=a[i]==W^a[i-1]==W^s[i]=='o'?83:W;if(!strncmp(a,a+n,2))a[n]=0,puts(a),exit(0);}main(){scanf("%d%s",&n,&s);s[n]=*s;s[n+1]=s[1];f(83,83);f(83,W);f(W,83);f(W,W);puts("-1");}```

Unoptimized Assembly Code:

Given the following C code and unoptimized assembly code, your task is to generate highly optimized x86-64 assembly code.
C Code:

```c
W=87,i,n;char a[100002],s[100002];f(x,y){*a=x;a[1]=y;for(i=0;++i<=n;)a[i+1]=a[i]==W^a[i-1]==W^s[i]=='o'?83:W;if(!strncmp(a,a+n,2))a[n]=0,puts(a),exit(0);}main(){scanf("%d%s",&n,&s);s[n]=*s;s[n+1]=s[1];f(83,83);f(83,W);f(W,83);f(W,W);puts("-1");}```
