how to make priority queue max heap code example
Example 1: min heap priority queue c++
#include<queue>
std::priority_queue <int, std::vector<int>, std::greater<int> > minHeap;
Example 2: priority queue max heap in java
PriorityQueue<Integer> queue = new PriorityQueue<>(10, Collections.reverseOrder());
PriorityQueue<Integer> pq =new PriorityQueue<>((x, y) -> Integer.compare(y, x));
PriorityQueue<Integer> pq = new PriorityQueue<Integer>(defaultSize, new Comparator<Integer>() {
public int compare(Integer lhs, Integer rhs) {
if (lhs < rhs) return +1;
if (lhs.equals(rhs)) return 0;
return -1;
}
});
