Java PriorityQueue is an unbounded Queue implementation that processes the items based on priorities. Custom ordering can be enforced with a Comparator.
using PII =pair<int,int>;autocmp = [&](constPII& a,constPII& b) {intsum1 = nums1[a.first] + nums2[a.second];intsum2 = nums1[b.first] + nums2[b.second];return(sum1 > sum2) || ((sum1 == sum2) && (a.first < b.first)); };// vitalpriority_queue<PII,deque<PII>...
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...
C++ Priority Queue 是一种常用的数据结构,用于解决优先级队列问题。而 Custom Comparator 则是一种高级的数据结构,允许用户自定义比较器,使得 Priority Queue 可以更加灵活地支持不同的优先级排序需求。在这篇文章中,我们将对 C++ Priority Quee 的 Custom Comparator 进行简要解读与分析。 首先,让我们来看一下 Prio...
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...
priority; const priorityQueue = new Heap(customPriorityComparator); // Initialize the priority queue with the tasks priorityQueue.init(tasks); // Iterator, the Java way, that will not consume the heap BUT does not guarantee to traverse the elements of the heap in any particular order. Barely ...
