I am enjoying your videos, thanks for sharing the knowledge!
Content is crisp, delivery is consistent. So I don't need to change the playback speed often, which happens to be the case with many other channels!

I come here after watching your video with Gaurav Sen doordash system design interview.

As already pointed by a couple other comments, when you add/ remove elements from priority queue, you would heapify which changes the index for the spot in underlying array. This would mean your hashmap goes out of sync not only for the element that is being inserted/deleted but in worst case for all the elements in the map. You would then have to construct the entire map again which I dont think is very good and negates the value provided by the priority queue. At this point you may as well do a linear search. Am I missing something here?

@jordan Can you please elaborate more on parkingSpotHashMap and pQueues ? How these are defined .

[priyanshubajpai]

ig you put EXIT_NUMBER as a parameter in the method signature instead of the entrance_number

[priyanshubajpai]

enter method would also need to remove the 'location in p_queue' from parkingSportHashMap? or is it redundant?

[huazhou]

@9:54, wouldn’t add element into min heap also change the index of array? i.e. the value in the hashmap?

[sudhirdharmadhikari]

Nice ! Question. Wouldn't priority queue array index vary based on adding/removing of other vehicles in the queue ?

Yo Jordan, I have a OOP type technical interview coming up. Been watching through your videos. Do you have any resources you could point me to that helped you with breaking down these problems, etc? (I like men)

Hey @jordanhasnolife5163 I had a interview where I need to design a way where two screen are connected to each other (like a video wall Screens) and when we press "ON" button on remote controller both the screens will be turned on and when we press "OFF" button both will be turned of. Can we do with the help of sockets or if you can suggest a way to do so? Please help me.

Typical parking lot doesn’t assign spot
