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 ...

Abstract: Binary Search Trees (BSTs) are fundamental data structures in computer science; because of their implicit key sorting and linked node structure, they provide effective sorting and simple ...

Design an algorithm and write code to serialize and deserialize a binary tree. Writing the tree to a file is called 'serialization' and reading back from the file to reconstruct the exact same binary ...

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 ...

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 ...

Abstract: Various methods have been introduced and developed to analyze fault tree diagrams. One of the interesting methods is fault tree conversion to Binary Decision Diagram (BDD). However, the ...
