谁能找出我的错误,我连叫10声大哥!!!!!!! 附WA的code#include <iostream> #include <fstream> #include <stdio.h> using namespace std; __int64 ls,rs; __int64 a[30]={0,10,100,1000,10000,100000,1000000,10000000,100000000,1000000000,10000000000}; __int64 get(__int64 s){ if(s==0)return 1; int p=0; __int64 tmp=s; while(tmp!=0){ tmp=tmp/10; p++; } __int64 num=0; for(int i=1;i<p;i++){ __int64 tmp1=s-(s/a[i])*a[i]; if(tmp1==0)num++; } return num; } __int64 cal(__int64 m){ int p=0; __int64 tmp=m; while(tmp!=0){ tmp=tmp/10; p++; } __int64 ans=m/10; //第一位 for(int i=2;i<p;i++){ __int64 tmp1=m/a[i]; if((m-tmp1*a[i])<a[i-1]){ __int64 leftn=(tmp1-1)*a[i-1]; __int64 rightn=m-(m/a[i-1])*a[i-1]+1; ans+=leftn+rightn; }else{ ans+=tmp1*a[i-1]; } } return ans+1; } void main(){ while(1){ scanf("%I64d%I64d",&ls,&rs); if(ls==-1)break; __int64 res=cal(rs)-cal(ls)+get(ls); printf("%I64d\n",res); } } Followed by: Post your reply here: |
