Web4 dec. 2024 · LCA in BST (25 分). The lowest common ancestor (LCA) of two nodes u and v in a tree T is the deepest node that has both u and v as descendants. Given any two nodes in a binary search tree (BST), you are supposed to find their LCA. WebInput: root = [0,1,3,null,2] Output: [2] Explanation: The deepest leaf node in the tree is 2, the lca of one node is itself.

Web28 sep. 2024 · Recursive solution: LCA of a binary search tree. Conceptually this is how it works. We just need to find if there exists a node in the tree which is less than (or equal) than any of the given nodes and greater than (or equal) than any of the given nodes. If it exits then it is the least common ancestor (LCA). WebOptimal Approach for Lowest Common Ancestor in Binary Search Tree. Using the properties of BST, the LCA can be found in much lesser time complexity. Traverse the BST starting from the root (Initialize curr as root). If the current node’s value lies between n1 and n2 (both inclusive), then this is the LCA.
