#include
using namespace std;
void generate_subsequence(char* in, char* out,int i,int j) {
if(in[i]==’\0’)
{
out[j]=’\0’;
cout<<out<<" ";
return;
}
//out[j]=in[i];
generate_subsequence(in,out,i+1,j);
out[j]=in[i];
generate_subsequence(in,out,i+1,j+1);
return;
}
int main() {
char input[1000];
cin>>input;
char output[1000];
generate_subsequence(input,output,0,0);
}

Hey @tarunasree123
Say array size is n
then total subsequence will be 2^n
