            call stack for recursion logic is not behaving proper in java
            Asked 2021-May-27 at 05:33

            I am writing a program to get Sum of depth for a given binaryTree. It's returning proper value with instance value but returning wrong value(greater than expected) if I am printing the returned value from the method. Code with output is as below.
            Note: I am having the right solution also but I am posting this solution to understand what wrong happing with the call stack of the recursion. My expectation was in the last stack memory the final value will persist that will be returned to the caller method it returning a different value.

            ANSWER

            Answered 2021-May-27 at 05:33

            The base case should return depth rather than the accumulated depthSum.

            The base case is asking:

            What is the depth sum of a subtree that has no child nodes?

            It is the depth of that subtree! depthSum would include all the depths of the nodes that we have counted, some of which are not in the subtree that we are asking about, so is incorrect.

            Also, the recursive case should also add depth to the sum of both subtrees.

            The recursive case is asking:

            What is the depth sum of a subtree with two sub-subtrees?

            It is the sum of the depth sum of those sub-subtrees, plus the depth of the subtree itself!

            Also note that you forgot the case when exactly one of root.left and root.right is null.

            After handling those cases, the code would look like:

            However, this code only creates the right nodes of the binary tree. What is wrong with my code?

            Some of the issues are:

            • Your code has a mix of BinaryNode and Node. I will assume Node.
            • The first code block has a constructor without a name -- that is a syntax error.
            • root should not be initialised as new Node, but as the return value from a call to BinaryTree
            • obj should not be defined in a scope that is larger than the BinaryTree function, as you will keep reusing the same object over and over in each recursive call, which will have devastating effects on the algorithm. You don't even need this variable.

            Since you defined a non-default constructor, the compiler will not generate a default constructor, see https://en.cppreference.com/w/cpp/language/default_constructor for more info. To solve this, see default constructor not generated?.

            I'm able to delete node successfully with no child or one child but unable to delete node with two children.

            In node with two children I'm using approach where I swap the value of targeted node with it's leaf child and then trying to delete the leaf node. But while deleting it's giving error exited with code=3221225725 in 0.474 seconds I also tried creating other functions to delete it but end up getting the same.

            I've tried removing delete and the code is running just fine and the value is swapped successfully too! I've also used same approach for Binary Search Tree and it was working just fine!

            I'm going to post a section in Java, but I assume if you're doing BinaryTrees you can read it haha. Anyways, it looks like you have Node defined which is equivilent to my BinaryTreeNode and then you want to have a constructor that takes in a left and right tree node to recursively define the tree.

            If your tree nodes store their parent it is possible to find the following node from any position and you could do a while loop on that but it will take more time than the recursive form (because the call to next() will require more than just a single node step half the time where the recursive-descent never takes more than a single step to find the next node to free).
