rt,

#include <bits/stdc++.h>
#define int long long

using namespace std;

const char space=' ';

signed main(){
#ifdef LOCAL
    freopen("decode.in","r",stdin);
    freopen("decode.out","w",stdout);
#endif
    ios::sync_with_stdio(false);
    int k;
    cin>>k;
    while(k--)
    {
        int n,e,d;
        cin>>n>>d>>e;
        int m=n-e*d+2;
        int left=0,right=m/2;
        while(left+1<right)
        {
            int mid=left+(right-left)/2;
            if(mid*(m-mid)<=n)
                left=mid;
            else
                right=mid;
        }
        if(left*(m-left)==n)
            cout<<left<<space<<m-left<<endl;
        else
            cout<<"NO"<<endl;
    }
    return 0;
}

大样例过了.

好人一生平安
