Pre-order traversal while duplicating nodes and values can make a complete duplicate of a binary tree. It can also be used to make a prefix expression (Polish notation) from expression trees: traverse the expression tree pre-orderly.
In-order traversal is very commonly used in binary search trees because it returns values from the underlying set in order, according to the comparator that set up the binary search tree (hence the name).
Post-order traversal while deleting or freeing nodes and values can delete or free an entire binary tree. It can also generate a postfix representation of a binary tree

It's amazing how his video is still helping people after 3 years! A huge round of applause for this amazing teacher 👏👏👏 He helped me with my DBMS subject as well! This comment is to tell him that not just GATE aspirants but college/university students watch him too! I guess majority might be us college students🤣 even though the channel name is Gate Smashers. Once again, a very great and helpful video😇
