Build a Tree is a popular coding challenge that tests your knowledge of data structures and algorithms. It involves creating a tree data structure and performing various operations on it. In this article, we will discuss the answers to mission 3 of the Build a Tree challenge.
Mission 3 focuses on finding the lowest common ancestor (LCA) of two nodes in a binary tree. The LCA is the highest node that is a common ancestor of both nodes. To solve this mission, you need to implement a function that takes in a binary tree and two nodes and returns the LCA.
There are several approaches to solving this problem. One common approach is to traverse the tree from the root and check if both nodes are descendants of the current node. If they are, we continue traversing down the left and right subtrees until we find the LCA. Another approach is to use a recursive function that checks if a node is a descendant of another node and returns the first common ancestor it finds.
Understanding and implementing the solution to this mission will not only help you with coding challenges but also improve your knowledge of tree data structures and algorithms. It is important to practice and solve coding challenges like Build a Tree to sharpen your problem-solving skills and become a better programmer.
