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

```c
#include<stdio.h>

int main(){
		int n,i,ans,k=0;
		char s[101],t[101];
		scanf("%d",&n);
		ans=n*2;
		scanf("%s",s);
		scanf("%s",t);
		for(i=0;i<n;i++){
				int j;
				for(j=n-i-1;j<n;j++){
						if(s[j]!=t[j-n+i+1])break;
				}
				if(j==n)k=i+1;
		}
		printf("%d\n",ans-k);
		return 0;
}
```
