分析：

      小学数学题，直接用模拟做

 

代码：

#include<cstdio>#include<string>#include<cstring>#include<cmath>#include<iostream>#define LL long longusing namespace std;int n,u,d;int main(){   // freopen("in.txt","r",stdin);int ans,s;while(scanf("%d%d%d",&n,&u,&d)!=EOF){        if(!n) return 0;        ans=0;        for(int i=0;i<n;){            i+=u;            ans++;            if(i>=n) break;            i-=d;            ans++;        }        printf("%d\n",ans);}return 0;}
