This is the 2nd Video of our Recursion Playlist.
In this video we will try to solve an easy string problem - Construct String from Binary Tree (Leetcode 606).
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.

Approach Summary :
It uses a recursive approach to traverse the tree in pre-order. The resulting string includes node values and parentheses to indicate the tree structure. Leaf nodes are represented by their values, nodes with only a left child have the left child's representation in parentheses, nodes with only a right child have an empty pair of parentheses followed by the right child's representation, and nodes with both children have both representations enclosed in parentheses.
