@shivamchef
unordered set means it completely unordered… adding one element can change order of all other elements…
So if you insert elements while you are using for each loop then there will be lot of mess…

here is your AC solution
check this code and you’ll understand the problem…

Code 
#include<bits/stdc++.h>
using namespace std;

#define ll long long int
#define FIO ios_base::sync_with_stdio(false);cin.tie(0);cout.tie(0)
#define mod 1000000007

int main() {
   FIO;
   int t,n,k,i,j;
   unordered_set<int> v;

   v.insert(0);
   v.insert(5);
   v.insert(8);

   for(auto it:v)
      cout << it << " ";
   cout << endl;

   v.insert(4);

   for(auto it:v)
      cout << it << " ";
   cout << endl;

   v.insert(10);

   for(auto it:v)
      cout << it << " ";
   cout << endl;

   return 0;
}

Haha really ? Is that the third level ? How to achieve that ?

You need magical super powers … if you don’t have them, then you need to convince the ‘Chef’ that you deserve those magical powers…and he’ll give it to you :heart_eyes::heart_eyes::heart_eyes::heart_eyes::heart_eyes:

Maybe I should try convincing pseudo admin @vijju123 ( credits to @aryanc403 for calling him that) for giving me trust level three… :joy:
