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

// qsortで用いる比較用関数．*a<*bならaが先になる．
int compare(const void* a, const void* b) {
    return *(int*)a - *(int*)b;
}

int revcompare(const void* a, const void* b) {
    return *(int*)b- *(int*)a;
}

int main(void)

    int x = 0;
    int N;

    scanf("%d", &N);
    char* s = (char*)malloc(sizeof(char) * (N+1));
    scanf("%s", s);


    int max = 0;
