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 0:00 - Introduction 1:35 - Complete the given tree 2:23 - Basic technique 2:54 - Solution with example ►Data Structure (Complete Playlist):    • Data Structure   Other subject-wise playlist Links: -------------------------------------------------------------------------------------------------------------------------------------- ► Operating System :    • Operating System (Complete Playlist)   ►Database Management System:    • DBMS (Database Management system) Complete...   ► Theory of Computation    • TOC(Theory of Computation)   ►Artificial Intelligence:    • Artificial Intelligence (Complete Playlist)   ►Computer Networks (Complete Playlist):    • Computer Networks (Complete Playlist)   ►Computer Architecture (Complete Playlist):    • Computer Organization and Architecture (Co...   ►Structured Query Language (SQL):    • Structured Query Language (SQL)   ►Discrete Mathematics:    • Discrete Mathematics   ►Compiler Design:    • Compiler Design (Complete Playlist)   ►Number System:    • Number system   ►Cloud Computing & BIG Data:    • Cloud Computing (Complete Course)   ►Software Engineering:    • Software Engineering   ►Design and Analysis of algorithms (DAA) (Complete Playlist):    • Design and Analysis of algorithms (DAA)   ►Graph Theory:    • Graph Theory   ►Programming in C:    • C Programming   ►Digital Logic:    • Digital Logic (Complete Playlist)   --------------------------------------------------------------------------------------------------------------------------------------- Our social media Links: ► Subscribe to us on YouTube:    / gatesmashers   ►Subscribe to our new channel:    / @varunainashots   ► Like our page on Facebook:   / gatesmashers   ► Follow us on Instagram:   / gate.smashers   ► Follow us on Instagram:   / varunainashots   ► Follow us on Telegram: https://t.me/gatesmashersofficial ► Follow us on Threads: https://www.threads.net/@gate.smashers -------------------------------------------------------------------------------------------------------------------------------------- ►For Any Query, Suggestion or notes contribution: Email us at: [email protected] #Preorder#Inorder#Postorder#DataStructure
