If this is true where is the core of that star, either a neutron star or a black hole should exist near by, right?

I've tackled a lot so far! I've created methods to delete, get the weight, and sort the tree by name. My goal is to have my switch criteria change how the tree is sorted, either by weight or by name. I haven't figured out how to implement it within my switchCriteria() method, so I've been...

I am having a hard time implementing comparing a given String name with the names of the Dog objects in my binary Search Tree. The problem comes from my containsRecursive() method. I need to use a String name to find if the name is already in my Binary Search Tree.Here's what I've tried...

The thread https://www.physicsforums.com/threads/how-close-is-earth-to-the-closest-black-hole.939912/ reached a conclusion that there is a 65% confidence level that there is one black hole within 50 ly of Earth. The link http://www.solstation.com/stars/s20ly.htm says there are 25 stars bigger...

Hi, a very basic question: what is a good intuitive way to understand the importance of a reference prior? In the context of a signal search. Bellow, I also try to give the way I understand the approach in a Bayesian analysis (roughly): 1. You have your likelihood model L = p(x_{obs} | \lambda...

What happens, if instead of having any pointer pointing to a node's parent, we had pointer pointing to the node's successor? We know, that Searching would remain the same. But in my opinion Insertion and Deletion would change. This would happen, because in insertion, we would be needed to find...

My instructor asked us to create a binary search tree in python that supports variables. i.e. the tree will have variables inside, and the user can get the values for those variables by looking for the name of that variable. I don't really know how to implement this. What I have so far: class...
