I was doing a leetcode question https://leetcode.com/problems/lowest-common-ancestor-of-a-binary-tree-ii/ and I am confused on how parameters for a method get stored during a recursive call. If a node gets visited, I wanted to save it’s state that it was visited. When I send two variables, when the stack is getting unwinded the updated variable values are being lost. But if I send
Closed. This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 4 months ago. Improve this question I have a Node class used to represent a tree structure. Within this class, I’ve defined a print method that
I have to make a programm that counts the nodes bigger than their sons without including the leaf nodes for example: This is my approach: But I can’t see the error Answer Assuming info is an int, this could work for you. I haven’t tested the code, so let me know if there are issues.
I have a class Employee which has a tree structure with property team Using Java lambdas I need to flat this tree into same level list while converting Employee class into the following ConvertedEmployee while storing names in dedicated lead and subordinates properties. So ConvertedEmployee is in some sense a node which keeps parent and children. And I need to
I am working on the LeetCode problem 297. Serialize and Deserialize Binary Tree: Serialization is the process of converting a data structure or object into a sequence of bits so that it can be stored in a file or memory buffer, or transmitted across a network connection link to be reconstructed later in the same or another computer environment. Design
My task is to change the values of nodes to their heights in a binary tree. By the condition of the task, you need to change all the values in 1 pass of the tree, but you can violate this condition …
Problem Statement You are given a pointer to the root of a binary tree. Print the top view of the binary tree. You only have to complete the function. My Code: The two if statements are executed every time the function is called, but I need only one of them to execute. I tried switch but its giving constant expression
I’ve a list of paths like this So from this list of paths (Stings) I need to crete a Java Tree structure that has folders as nodes and files as leaf (there wont be empty folders as leaf). What I need I think is the add method where I pass to them a String (path of the file) and it
