Web2 nov. 2012 · This problem is called Lowest Common Ancestor (LCA) problem. (Google it) One query can be answered by simply climbing up along their parent links until they meet: The first step is to let the lower node climb until they are in the same height. The second step is to let them climb simultaneously until they meet at the same node. Web6 dec. 2024 · Lowest Common Ancestor (LCA): The lowest common ancestor is defined between two nodes x and y as the lowest node in T that has both x and y as descendants (where we allow a node to be a descendant of itself. Examples: Consider the following Binary Tree Example 1: Input: x = 4 , y = 5 Output: 2 Explanation: All ancestors for 4,5 …
