The king of Sikinia was very satisfied with your work documenting his kingdom's wealth distribution. As a result, he has put you in charge of improving the country's road system. Various portions of the country are well reachable from existing roads, while others are cut off from the transportation network. . . .

The king of the distant country Sikinia has tasked you to keep records of the individual wealth of his people. There are $n = 2^k$ people living in Sikinia. However, the king does not care about every individual's wealth, but the net-worth of every $2^i$'th wealthiest person. Your . . .

This article is part of a series on coding interview topics. Design a type that can only be instantiated once. In software engineering, the singleton pattern is a design pattern that restricts the instantiation of a type to only one object. public class Foo { private static final Foo fooInstance = new . . .

It's always boggled my mind how statistics plays a role in the runtime analysis of various algorithms. The two seemingly distinct fields of Computer Science and Statistics mesh in a very surprising way - enabling one to make strong statements regarding the asymptotic complexity of an algorithm. In this article . . .

This post is a part of a series on stochastic theory. In this article, we will work through a standard theory problem on the Bernoulli-Laplace model of diffusion. I presume here that you have a basic understanding of what a Markov chain is. Problem Context Let's consider two urns, each . . .
