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

```c
#include <stdio.h>

int main(void) {
	int n, i, j, r, x;
	char s[111], t[111];
	
	scanf("%d %s %s", &n, s, t);
	
	r=2*n;
	
	for(i=1;i<=n;i++){
		x=n-i;
		for(j=0;j<i;j++){
			if(s[j+x]!=t[j])
			break;
			if(j==i-1)
			r=2*n-i;
		}
	}
	printf("%d\n", r);
	return 0;
}
```
