水了一个优先队列的题目

#include <iostream>
#include <queue>
using namespace std;

int main()
{
  priority_queue<int>q;
  int n, m, i;
  while(cin>>n)
    {
      for( i = 0; i < n; i++)
        {
          cin>>m;
          q.push(m);
        }
      while(q.size() >= 2)
        {
          int x = q.top();
          q.pop();
          int y = q.top();
          if(x > y)
            {
              int z = x - y;
              q.push(z);
            }
        }
      int sum = q.top() * n;
      while(!q.empty())
        {

          q.pop();
        }
      cout<<sum<<endl;
    }
  return 0;
}
