How to generate all the possible subsets of a set ?
#include<bits/stdc++.h>
using namespace std;
int main()
{
ios_base::sync_with_stdio(0);
cin.tie(0);
int n;
cin>>n;
vector<char>v(n);
for(int i=0;i<n;i++){
cin>>v[i];
}
cout<<"All Possible subset:\n";
for(int i=0;i<(1<<n);i++){
for(int j=0;j<n;j++){
if(i&(1<<j)){
cout<<v[j]<<" ";
}
}
cout<<'\n';
}
return 0;
}
