Is there a specific reason you want to implement your own priority queue? Often the standard library implementation is enough.
No , actually library is enough but i don't know where can i find all PQ libraries at one place . do u have any source , from where u studied PQ . if possible please also suggest operator overloading blogs / tutorials .
Redux
I usually just refer to one of the standard language references.
cpp
java
actually i was studying dijkartas ,
:https://www.geeksforgeeks.org/dijkstras-shortest-path-algorithm-using-priority_queue-stl/
i find a very weird syntax **** priority_queue< iPair, vector , greater > pq;
i couldn't find it anywhere , does the blog you given above contains everything about PQ ?
That is the syntax of templates in cpp.
Here is the language reference to templates in general https://en.cppreference.com/w/cpp/language/templates.
Also the previous link to cpp priority queues does describe the parameters for the priority queue template.
Thanks Redux
This is a good link to learn C++: https://www.learncpp.com/
