Subtree in N-ary Tree | GFG | POTD | 1st May 2023 | N-ary tree | Java | C++ | Problem Of The Day
The video solves Problem Of The Day question " Subtree in N-ary Tree " asked on GeeksForGeeks on 1st May 2023 .
We are given the root of an n-ary tree and we need to find the number of duplicate subtrees in the tree. Two trees are considered duplicates if they have the same structure and the same node values. So, we need to find all the subtrees that have the same structure and node values.
To solve this problem, we can use a recursive approach. We will traverse the n-ary tree in a postorder manner and for each node, we will construct a string that represents the subtree rooted at that node. We will also keep track of the frequency of each subtree.
