【CF1028B】Unnatural Conditions（构造）

题意：给定n与m，要求构造两个长度不超过2230的数字x,y使得x,y各自的数位和>=n，x+y的数位和<=n

思路：

 #include<cstdio>

 #include<cstring>

 #include<string>

 #include<cmath>

 #include<iostream>

 #include<algorithm>

 #include<map>

 #include<set>

 #include<queue>

 #include<vector>

 using namespace std;

 typedef long long ll;

 typedef unsigned int uint;

 typedef unsigned long long ull;

 typedef pair<int,int> PII;

 typedef vector<int> VI;

 #define fi first

 #define se second

 #define MP make_pair

 #define N   2100000

 #define MOD 1000000007

 #define eps 1e-8

 #define pi acos(-1)

 int read()

 {

    int v=,f=;

    char c=getchar();

    while(c<||<c) {if(c=='-') f=-; c=getchar();}

    while(<=c&&c<=) v=(v<<)+v+v+c-,c=getchar();

    return v*f;

 }

 void swap(int &x,int &y)

 {

     int t=x;x=y;y=t;

 }

 int main()

 {

  //   freopen("cf1028B.in","r",stdin);

    // freopen("cf1028B.out","w",stdout);

     int n,m;

     scanf("%d%d",&n,&m);

     for(int i=;i<=;i++) printf("");

     printf("\n");

     for(int i=;i<=;i++) printf("");

     printf("");

     return ;

 }
