Is there any efficient algorithm for traversing a Heap-Based Priority Queue?
I have implemented a Heap-Based Priority Queue in Java but my challenge now is implementing an efficient Iterator that has a definite (increasing or decreasing) order of traversal. Is there any algorithm that does this at constant auxiliary space and time complexity of O(n)? The O(nlogn) is quite trivial. Als…

Java Iterator – infinite loop
What am I doing wrong? Why does this iterator keep running? The feasibility function checks if the element is viable, if yes assign the element to the list. Then the solution checks if this is the ‘algo’ solution and returns the list, else check the next element in the list. Answer next should alw…

I am a Java user and I am getting into C++ and in Java it allows classes to reveal Iterable types so clients can traverse some instance’s collection of data. Is there any way to obtain this …
How to add an object during ListIterator (reversed) iteration properly?
I have been asked from my professor to add an object in the middle of an ArrayedList<Employee> using listiterator. I have tried doing in the following way first: But this produces a seemingly infinite number of iterations where li.nextIndex() gets stuck on 5. I have verified this with the debugger and t…
Iterator hasNext for the last record fetching
As per my understanding, i.hasNext() method checks whether the next entry exists or not and returns true or false. And the i.next() method above here, will display the current linkedList record and then increments/moves to the next record. If we are in the last record, i.hasNext() is false, how is it still ex…
