Which type of tree node's in-order successor of a node with two children is the left-most child?Note: This kind of question will be helpful in clearing Infosys recruitment.Marks : 1Negative Marks : 0Answer hereRight subtreeLeft subtreeBoth right and left subtreesNone of the mentioned options
Solution
The in-order successor of a node with two children in a binary tree is the left-most child in the Right subtree.
Here's the step-by-step explanation:
-
If a node has a right subtree, then the in-order successor is the left-most node in the right subtree.
-
If a node does not have a right subtree, and it is the left child of its parent, then the parent is the in-order successor.
-
If a node does not have a right subtree, and it is the right child of its parent, then the in-order successor is the parent of the nearest ancestor which has a left child.
So, the answer to your question is "Right subtree".
