【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:

 1 #include<cstdio>
 2 #include<cstring>
 3 #include<string>
 4 #include<cmath>
 5 #include<iostream>
 6 #include<algorithm>
 7 #include<map>
 8 #include<set>
 9 #include<queue>
10 #include<vector>
11 using namespace std;
12 typedef long long ll;
13 typedef unsigned int uint;
14 typedef unsigned long long ull;
15 typedef pair<int,int> PII;
16 typedef vector<int> VI;
17 #define fi first
18 #define se second 
19 #define MP make_pair
20 #define N   2100000 
21 #define MOD 1000000007
22 #define eps 1e-8 
23 #define pi acos(-1)
24

27 
28 int read()
29 { 
30    int v=0,f=1;
31    char c=getchar();
32    while(c<48||57<c) {if(c=='-') f=-1; c=getchar();}
33    while(48<=c&&c<=57) v=(v<<3)+v+v+c-48,c=getchar();
34    return v*f;
35 }
36 
37 void swap(int &x,int &y)
38 {
39     int t=x;x=y;y=t;
40 }
41 
42 
43 int main()
44 {
45  //   freopen("cf1028B.in","r",stdin);
46    // freopen("cf1028B.out","w",stdout);
47     int n,m;
48     scanf("%d%d",&n,&m);
49     for(int i=1;i<=2230;i++) printf("8");
50     printf("\n");
51     for(int i=1;i<=2229;i++) printf("1");
52     printf("2"); 
53     return 0;
54 }
