 4         vector<int> deckRevealedIncreasing(vector<int>& deck)
 5         {
 6             sort(deck.begin(),deck.end());

 8             int deckend = 0;
 9             int flag = 1;
10             for(int i = 0;deckend < deck.size();i = (i+1)%(deck.size()))
11             {
12                 if(!rnt[i])
13                 {
14                     if(flag) rnt[i] = deck[deckend++];
15                     flag = !flag;
