CPT 307: Starting to understand algorithm selection

As it turns out, there is a specific science to selecting the best algorithm to apply to data within a program.  When I first started my Data Structures & Algorithms class, I was excited to learn about different algorithms, and how to efficiently store and sort data using advanced data structures.  What I learned was that there are a great many different algorithms to both search and sort information stored in arrays.  Some websites, such as geeksforgeeks.org, have entire lists of different algorithms each with differing complexities, and each tailored for a specific use.  The computer science community describes algorithm efficiency using two different measures of complexity.  Time complexity is a function relating the number of actions (n) that will be performed on an array (a[]).  There are many different kinds of actions that an algorithm can perform on an array of data.  Time can mean the number of memory accesses performed, the number of comparisons between integers, the nu

CPT 307: Java Newbie to Newbie

     For our first assignment in CPT 307: Data Structures & Algorithms, we were tasked with installing the Java Development Kit (JDK) and the NetBeans IDE.  Installing the JDK was straightforward and painless.  It was as simple as downloading the installer and following the installation wizard.  NetBeans was a slightly different story.  There were several different packages to download; I chose the package with the most language support.  In hindsight, I probably should have downloaded only the package supporting Java, saving the other packages for when I actually use the other tools.  After completing the NetBeans install, I kept getting an error about “GlassFish” whenever I tried creating a new project.  I attempted to search the forums for a fix but found the NetBeans forums to be extremely confusing, and I could not find a solution to the issue.  So I decided to search the internet for a different IDE to work with.  What I found was the IntelliJ IDEA.  JetBrains packed their I

CPT 200: Fundamentals of Programming Languages

    During my quest to obtain a Bachelor of Information Technology from Ashford University, my fourth class was CPT 200: Fundamentals of Programming Languages.  For that class, the programming language that is taught is Python 3.     On the first week of class, we were asked to create code that would ask a user to input several pieces of information about any specific employee.  We were to use the variables: employeeName, employeeSSN, employeePhone, employeeEmail, and employeeSalary.  After the data was inputted, it needed to be printed on the screen.  Below was what I turned in for Functionality 1:     During the second week of class, we were to read two chapters: Chapter 3: Types and Chapter 4: Branching.  These chapters introduced us to the different types of variables that can be used within Python as well as how to use branching in your scripts. For the second functionality, we were instructed to adjust our code to allow for 5 different employees to be input into the system
