Whenever you use custom type(class) in priority_queue you have explicitly write the compare function for it!!
But here why do you need info like array index etc!, just implement it normally as integer.

why have you done operator overloading. can’t we just make our comparator fuction and pass it as an argument like we pass in sort function tom sort arrays…sort(arr,arr+n,mycompare).

Yes but in sort function!! we write comparators in struct/class when passing to STL containers
