priority queue clear method

Question

How do I delete all elements from a priority queue? That means how do I destroy a priority queue? advanced thanks for your answer. Is there any clear- or erase-like method

Answer 1

there is no clear method supported for priority_queue in c++ but, this below is a good method to clear the priority_queue and has O(log(n)) time

while (!pq.empty())
      pq.pop();
