I don't think so.

Given the value of m and x, you will have to find the value of the maximum income v, which is effectively (after deducting the tax) less than someone earning less than v.


According to problem statement, v must bigger than m.
If I am wrong, correct me.

PS. I change
Code: Select all
if(n<=m)
  puts("Not found");

to
Code: Select all
if(n<m)
  puts("Not found");


still WA....

even if v==m its effective income may less then m-1,
so solution v is valid as i think.

To hi!man!

For input "100 67", your code outputs 300

But I think the answer is 299

by the way, I think
if(n*100%(100-x)==0)
n--;
exist a problem

Hope it helps :)

What's wrong with my code :

Code: Select all
#include <iostream>
#include <bitset>
#include <algorithm>
#include <cstdio>
#include <cstdlib>
#include <string>
#include <cstring>
#include <vector>
#include <map>
#include <queue>
#include <deque>
#include <stack>
#include <cctype>
#include <set>
#include <cmath>
#include <climits>
#include <sstream>
#include <fstream>
#include <list>
#include <functional>
#include <utility>
#include <iomanip>
#include <ctime>

using namespace std;

#define SZ size()
#define pp push_back

typedef long long LL;
typedef vector <int> vi;
typedef vector <double> vd;
typedef vector <vi> vvi;
typedef vector <string> vs;
typedef pair<int,int> pii;
typedef vector <LL> vll;


int main () {
    int n,m;
    while (scanf("%d %d",&n,&m) != EOF) {
          if (!n && !m) return 0;
          if (m==100 || m == 0 || n == 1) { printf("Not Found\n"); continue;}
          double temp = (double)m/100.0;
          temp = 1.0-temp;
          temp = (n-1) / temp;
          int ret = (int) temp;
          ret++;
          if (ret < n) { printf("Not Found\n"); continue;}
          bool stat = false;
          while (true) {
                double t = (ret*((double)1-m/100.0));
                //cout << ret << " " << t << "\n";
                if (t < ((double)n-1) && ret >= n) { printf("%d\n",ret); stat = true; break;}
                ret--;
                if (ret < n) break;
          }
          if (!stat) printf("Not Found\n");
    }
    return 0;
}

Too Complex Code for a simple problem..

v < 100*(m-1)/(100-x)
[spoiler ? then i will remove it]


it is enough.. and can be solved without using double..

To everybody who got stuck, it is necessary to check whether you calculated v is larger than or equal to m.

if (v<m)
cout<<"Not found\n";
else
cout<<v<<endl;
Impossible is Nothing.
