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,ryou = 0,first = 0,last = 0,AB = 0,a,i,j;
    char S[12];
    scanf("%d",&N);
    for (i = 0;i < N;i++) {
        scanf("%s",S);
        a = strlen(S);
        for (j = 0;j < a - 1;j++) {
            if (S[j] == 'A' && S[j + 1] == 'B') AB++;
        }
        if (S[0] == 'B' && S[a - 1] == 'A') {
            ryou++;
        } else if (S[0] == 'B') {
            first++;
        } else if (S[a - 1] == 'A') {
            last++;
        }
    }
    if (first == 0 && last == 0 ) {
        if (ryou == 0) {
            printf("%d\n",AB);
        } else {
            printf("%d\n",ryou + AB - 1);            
        }
    } else if (first <= last) {
        printf("%d\n",first + ryou + AB);
    } else {
        printf("%d\n",last + ryou + AB);
    }
    return 0;
}
```

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,ryou = 0,first = 0,last = 0,AB = 0,a,i,j;
    char S[12];
    scanf("%d",&N);
    for (i = 0;i < N;i++) {
        scanf("%s",S);
        a = strlen(S);
        for (j = 0;j < a - 1;j++) {
            if (S[j] == 'A' && S[j + 1] == 'B') AB++;
        }
        if (S[0] == 'B' && S[a - 1] == 'A') {
            ryou++;
        } else if (S[0] == 'B') {
            first++;
        } else if (S[a - 1] == 'A') {
            last++;
        }
    }
    if (first == 0 && last == 0 ) {
        if (ryou == 0) {
            printf("%d\n",AB);
        } else {
            printf("%d\n",ryou + AB - 1);            
        }
    } else if (first <= last) {
