This is the 5th Video of our Playlist "TRIE: Popular Interview Problems" by codestorywithMIK
In this video we will try to solve a good practice Trie problem : Replace Words | Using TRIE | Uber | Leetcode 648 | codestorywithMIK
I will explain the intuition so easily that you will never forget and start seeing this as cakewalk EASYYY.
We will do live coding after explanation and see if we are able to pass all the test cases.
Also, please note that my Github solution link below contains both C++ as well as JAVA code.

Summary :
TrieNode Class: This inner class represents a node in the trie. Each node has an array of 26 children (one for each lowercase English letter) and a boolean isEndOfWord to mark the end of a word.
Solution Constructor: Initializes the root of the trie.
insert Method: Inserts a word into the trie by traversing each character and creating new TrieNode objects as necessary.
search Method: Searches for the shortest prefix in the trie that matches the start of the given word. If no such prefix is found, it returns the original word.
replaceWords Method: Takes a list of dictionary words and a sentence. It first inserts all dictionary words into the trie. Then, it splits the sentence into words, searches for each word in the trie, and builds the resulting sentence with replaced words.
This Java implementation should match the functionality of your original C++ code.
