🔥 *LeetCode Daily POTD #3841 – Palindromic Path Queries in a Tree | Java Solution*
In this video, we solve **LeetCode 3841: Palindromic Path Queries in a Tree**, a Hard-level problem involving tree traversal, bit manipulation, and efficient query processing.
The problem involves handling two types of queries on a tree:
*Update Query:* Change the character assigned to a node.
*Path Query:* Determine whether the characters on the path between two nodes can be rearranged to form a palindrome.
📌 *Concepts Used:*
*Bitmask:* Represent character frequencies using bits.
*Euler Tour:* Flatten the tree to support efficient subtree and path-related operations.
*Binary Lifting:* Find the Lowest Common Ancestor (LCA) efficiently.
*Segment Tree:* Maintain character information while processing updates and queries.
