Can you please help me with this question
#include
using namespace std;
void Subsequences(char *in, char *out, int i, int j){
if(in[i] == ‘\0’){
out[j] = ‘\0’;
cout<<out<<endl;
return;
}
//Ignore the ith character
Subsequences(in, out, i+1, j);
//Take the ith character in output array
out[j] = in[i];
Subsequences(in, out, i+1, j+1);
}
int main(){
int n;
cin>>n;
char in[n];
cin>>in;
char out[100];
Subsequences(in, out, 0, 0);
return 0;
}
this is my code but it is giving me output as
