i am unable to get the expected behaviour. I have wrote two custom comparators in the below code one for a vector and the other for a priority queue and the logic is same for both the comparators. how the output seems to be opposite, can anyone tell me the reason for this, any help...

Java PriorityQueue class is an unbounded Queue interface implementation that processes the queued items based on their priorities. The PriorityQueue is different from other standard queues that implement the FIFO (First-In-First-Out) algorithm. Priority Queue In PriorityQueue, the added items are retrie...
Das eingebaute Modulqueuein Python bietet eine Priority-Queue-Implementierung. Das Modul erlaubt uns jedoch nicht, einen benutzerdefinierten Komparator für die Prioritätswarteschlange anzugeben. Dies kann ein Problem sein, wenn wir eine andere Reihenfolge als die Standardreihenfolge für die Pr...

I am having problem writing a custom comparator for priority queue in C++. The elements' type in the queue ispair<long long,pair<long long, long long>>I want the queue to rank the elements with the smallestfirstelement first, and if there is a tie, rank the elements with the smallest...
