#include

string temp;

void subSequence(string S,int pointer){
if(pointer == S.size()){
cout<<temp<<" ";
return;
}

	subSequence(S,pointer+1);

    temp.push_back(S[pointer]);
    subSequence(S,pointer+1);

return;

}

int main(){
string S;
cin>>S;

subSequence(S,0);
cout<<endl;
 cout<<pow(2,S.size());

}

wrong ouput

hello @khemchandrs,
dont declare ur temp string as global,
pass it along with the function call.
becuase if u delcare it global then u will be appending in the same string and it will be tough to distinguish different subsequence.
