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>
#include <string.h>

int main(void) {
	int N;
	char s[128];
	char t[128];
	int i;
	if (scanf("%d", &N) != 1) return 1;
	if (scanf("%127s", s) != 1) return 1;
	if (scanf("%127s", t) != 1) return 1;
	for (i = N; i > 0; i--) {
		if (strncmp(s + N - i, t, i) == 0) {
			printf("%d\n", N + N - i);
			return 0;
		}
	}
	printf("%d\n", N + N);
	return 0;
}
```
