WebFirst the given nodes p and q are to be searched in a binary tree and then their lowest common ancestor is to be found. We can resort to a normal tree traversal to search for the two nodes. Once we reach the desired nodes p and q, we can backtrack and find the lowest common ancestor. Approach 1: Recursive Approach. Intuition WebThe lowest common ancestor is defined between two nodes v and w as the lowest node in T that has both v and w as descendants (where we allow a node to be a descendant of itself). - Wikipedia Your task in this problem is to find the LCA of any two given nodes v and w in a given tree T. ebt cardholder portal help
