I liked the discussion, particularly the negative height and which you took it as an advantage in the priority queue.

Wow. I struggled to understand this, and your explanation was simply the best of all of them. Thank you!

[@muraliKrishnaanimi]

isn't pq.remove() is costly? In c++ priorty_queue from stl has no option for remove(). any ideas to optimize?

[@TheTechGranth]

Time complexity of remove is O(logn) some way to handle in C++ stackoverflow.com/questions/19467485/how-to-remove-element-not-at-top-from-priority-queue

[@obulpathi2729]

Excellent m..you nailed it, thanks for explaining!!

[@ameynaik2743]

Nice solution, what is the approach to remove a specific element from pq in python? Looks like I need to use sortedList instead of heapq?
