The Binary Tree here is may not necessarily be a Binary Search Tree. The structure could be taken as - struct node { int data; struct node *left; struct node *right; }; The maximum solution I...

I have been going through the, "git merge-base", man page and I can't understand how multiple merge bases develop. Specifically, I'm hung up on the following illustration in the man page: When the...

There are tons of questions about the least common ancestor algorithm, but this one is different because I'm trying to determine the LCA at compile-time, and my tree is neither binary nor a search ...

I am trying to implement LCA for unrooted tree. I have given a tree (a connected undirected graph without cycles) and a sequence of queries about LCA for some root and two vertices. Every particula...

How are non binary trees typically represented? Trees where there is no limit to the number of children a node can have. Is it best to use a Adjacency Matrix or Adjacency List and just assume there...

So, I read this TopCoder tutorial on RMQ (Range Minimum Query), and I got a big question. On the section where he introduced the approach, what I can understand until now is this: (The whole appr...

So I have been looking into implementing a lowest common ancestor algorithm. I looked at many different algorithms (mainly variations of Trajan's solution or variations of the RMQ). I am using a ...

I was having a look at this question and then reading about Tarjan's least common ancestors algorithm. I never came across any applications of LCA algorithms before. Where are such LCA algor...

Following is my algorithm to find first common ancestor. But I don’t know how to calculate it time complexity, can anyone help? public Tree commonAncestor(Tree root, Tree p, Tree q) { if (covers(...
