CODE EXAMPLE FOR CPP

what do you mean by smallest anagram of a string

#include<iostream>
#include<algorithm>

using namespace std;

int main(){
string s,p;
int t;
cin>>t;
while(t--){
int j=0,i=0;
cin>>s>>p;

 while (i<s.length())
 {
    if(p[j]==s[i]){
    s.erase(s.begin()+i);
    j++;
    i=0;
    
  
    

  }
  else
  {
    i++;
  }
  
   
 }
 

int k=-1;
sort(s.begin(),s.end());
for (int i = 0; i < s.length(); i++)
{
  if(p[0]>=s[i])
  k=i;
}
s.insert(k+1,p);
cout<<s<<endl;
}
return 0;
}
