Abstract: The tree (hierarchical) structure is one of the elementary memory arrangements, used by numerous data structures – ranging from simple to relatively sophisticated ones. The most well-known ...

A Threaded Binary Tree improves binary tree traversal efficiency by replacing null pointers with in-order predecessor or successor links. This reduces stack usage and recursion overhead. Introduce a ...

Git isn’t hard to learn. Moreover, with a Git GUI such as Atlassian’s Sourcetree, and a SaaS code repository such as Bitbucket, mastery of the industry’s most powerful version control tools is within ...

Now that we’re getting into more complex data structures, having more complex operations, it’s helpful to have a tool for visualization. Here’s a tool developed by David Galles, formerly of University ...

A binary heap is a binary tree with two constraints: the heap order property and the structure property. The heap order property ensures that child nodes are always ordered with respect to their ...

ABSTRACT: In combinatorics, permutations are important objects with many operations. In this paper, we define a coupling product on permutations and prove that the space spanned by permutations is a ...

Merkle trees, also known as hash trees or binary hash trees, are tree-like data structures used in computer science. They are named after their inventor, Ralph Merkle, who proposed the concept in 1979 ...

The Chinese state-backed hacking group Volt Typhoon is behind attacks that exploited a zero-day flaw in Versa Director to upload a custom webshell to steal credentials and breach corporate networks.
