Abstract: Nowadays, transportation networks depend heavily on the technology known as vehicular ad hoc networks (VANETs). VANETs enhance traffic control and road safety while also enabling ...

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 ...

Given a binary tree, return an array where elements represent the bottom view of the binary tree from left to right. Note: If there are multiple bottom-most nodes for a horizontal distance from the ...

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 ...

Abstract: Zernike radial polynomials (ZRP) play a significant role in application areas such as optics design, imaging systems, and image processing systems. Currently, there are two kinds of ...

1. Assume the given binary tree contains all unique elements. 2. In a pair, print the smaller element first. Order of different pairs doesn't matter. Input format : The first line of input contains ...
