Priority Queue Comparison

Question

I\'m trying to declare a priority queue in c++ using a custom comparison function...

So , I declare the queue as follows:

std::priority_queue

        

Answer 1

you have to specify function type and instantiate the function in priority_queue constructor.

#include 

bool compare(int a, int b)
{
   return (a,
                              std::function> pq(compare);
