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;
}
