When there are many elements in the array, removing the elements who cause all elements to move to the previous place since we are copying to the previous elements position.. wouldn't that be O(N)?

Thanks Nivedita, I have been watching your videos for the last 6 months. I must have to say your way of explaining things is really good. Can you share your other profiles like LinkedIn and instagram?
