  • You need to define an ordering for nodes, either globally or by passing a parameter to the priority_queue. A bit more context will help you get a more useful answer. What is the definiton of node, and how do you want them to be ordered in the priority_queue? – john Jul 17 '20 at 08:23
  • you need to define how the nodes are ordered, this can be done using compare class and overriding operator function. – Ram Prabodh Induri Jul 17 '20 at 08:28
