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>

struct vector{int a; int b;};

int main(void) {
    int i, n, k, l, p, q, m;
    scanf("%d %d", &n, &k);
    if(k > (n-1)*(n-2)/2){printf("-1\n"); return 0;}
    struct vector v[n*(n-1)/2];
    for(i = 0; i < n-1; ++i){
        v[i].a = 1; v[i].b = i+2;
    }
    p = 2; q = 3;
    for(l = (n-1)*(n-2)/2; l > k; ++i, ++q, --l){
        v[i].a = p; v[i].b = q;
        if(q >= n){++p; q = p;}
    }
    m = i;
    printf("%d\n", m);
    for(i = 0; i < m; ++i){
        printf("%d %d\n", v[i].a, v[i].b);
    }
    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>

struct vector{int a; int b;};

int main(void) {
    int i, n, k, l, p, q, m;
    scanf("%d %d", &n, &k);
    if(k > (n-1)*(n-2)/2){printf("-1\n"); return 0;}
    struct vector v[n*(n-1)/2];
    for(i = 0; i < n-1; ++i){
        v[i].a = 1; v[i].b = i+2;
    }
    p = 2; q = 3;
    for(l = (n-1)*(n-2)/2; l > k; ++i, ++q, --l){
        v[i].a = p; v[i].b = q;
        if(q >= n){++p; q = p;}
    }
    m = i;
    printf("%d\n", m);
    for(i = 0; i < m; ++i){
        printf("%d %d\n", v[i].a, v[i].b);
    }
    return 0;
}```
