Knowing how to create a maze is as essential as breathing. So here is a simple algorithm to create mazes along with a link to a GitHub repository for its implementation in Swift. Algorithm 1. Start at cell (1, 1). 2. Find a neighbor at random that you haven’t yet . . . Read more
Problem Statement Given a graph G = (V, E), list all cycles within G. Algorithm 1. Compute a cycle basis of graph G = (V, E) * Find a minimal spanning tree (V, E’) of G, using Depth-first search (DFS) and its associated set of back edges * If e . . . Read more
Given S of size n and k, return the kth lexicographic permutation sequence. (Note: Given n will be between 1 and 10 inclusive.) For n = 10 variable symbols we have 10! possible permutations. The first step is to find the first symbol. If we fix a first symbol, then . . . Read more
