尼玛坑爹的水题，得注意细节，，，，

#include<iostream>#include<string.h>#include<string>#include<set>using namespace std;int main(){string s;while(cin>>s){multiset<int>Q;int n=s.size();int i=0;string s1="\0";while(i<n){   if(s[i]!='5') s1+=s[i];  else if(s1.size()>0&&s[i]=='5')//当s1不为空时才处理{int b=atoi(s1.data());Q.insert(b);        s1="\0";}   i++;}if(s1.size()>0) {int b=atoi(s1.data());Q.insert(b);}multiset<int>::iterator it;cout<<*(Q.begin());for(it=++Q.begin();it!=Q.end();++it)cout<<" "<<*it;    cout<<endl;}return 0;}
