Abstract: Alphabetic codes and binary search trees are combinatorial structures that abstract search procedures in ordered sets endowed with probability distributions. In this paper, we design new ...

Scientists have long relied on tree rings to learn about ancient solar storms—rare bursts of high-energy particles from the ...

The threat of hydrometeorological disasters in East Java in January 2026 is expected to be higher compared to the end of the year, in line with the increasing intensity of rainfall. In addition to ...

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 ...

How do you count rooted planar n n-ary trees with some number of leaves? For n = 2 n = 2 this puzzle leads to the Catalan numbers. These are so fascinating that the combinatorist Richard Stanley wrote ...

Minecraft Snapshot 25W09A introduces new fallen trees at various biomes. Now, the firefly bushes spawn in Mangrove biomes rather than badlands. Finally, the leaf litter blocks have become replaceable ...

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 ...
