Find the missing letter

Write a method that takes an array of consecutive (increasing) letters as input and that returns the missing letter in the array.You will always get an valid array. And it will be always exactly one letter be missing. The length of the array will always be at least 2.The array will always contain letters in only one case.Example:['a','b','c','d','f'] -> 'e'['O','Q','R','S'] -> 'P'(Use the English alphabet with 26 letters!)

Find The Parity Outlier

You are given an array (which will have a length of at least 3, but could be very large) containing integers. The array is either entirely comprised of odd integers or entirely comprised of even integers except for a single integer N. Write a method that takes the array as an argument and returns this "outlier" N.Examples[2, 4, 0, 100, 4, 11, 2602, 36] --> 11 (the only odd number)[160, 3, 1719, 19, 11, 13, -21] --> 160 (the only even number)

CSS Flexbox vs Grid: A Comparison

When it comes to modern web layout techniques, CSS Flexbox and CSS Grid are two powerful tools at a developer's disposal. Both have their strengths and are suited for different kinds of tasks. From my observations, beginners tend to learn just Flexbox and ignore Grid because Flexbox is easier to visualize and understand, which was also the same for me, but eventually, I discovered that I was missing out on a lot in terms of responsiveness and even beauty (surprisingly).Flexbox, or Flexible Box Layout, is designed for one-dimensional layouts. This means it excels in laying out items in a single...

What is a REST API?

A REST API (Representational State Transfer Application Programming Interface) is an architectural style for designing networked applications. It is a set of rules and conventions that govern how web services should communicate with each other. Here are some key points about REST APIs:Statelessness: REST APIs are stateless, which means that each request from a client to a server contains all the necessary information to understand and process that request. The server does not store any information about the client's previous interactions.Resources and URIs: REST APIs are built around the conce...

Python for Scientific Computing: My Journey Begins!

Hi Africoders, I'm excited to announce that I'm diving headfirst into the world of Python this semester! My goal? To harness the power of this popular language for scientific computing.Python's history is actually pretty interesting. Created in the late 1980s by Guido van Rossum, it was designed with readability and programmer productivity in mind. One of the key features that makes Python so beginner-friendly is that it's a **dynamically typed language**. This means you don't need to explicitly declare the data type of a variable before you use it, which can save a lot of time and effort when...

A Hilarious Look at My 4th Semester as Computing Student.

4th semester just hit me like a caffeine crash without the caffeine. My course load this time around is enough to make your head spin. We're talking web development, digital system design (think building the circuits behind the magic!), and then there's OOP with Java. Java! Don't even get me started.On the bright side, there's also scientific computing with Python – gotta love some Python, right? Plus, we're diving into computer architecture, the real brains of the operation. Linear Algebra II is back to haunt me (matrices, anyone?), and of course, there's statistics – because let's face it, i...

Digital System Design for Computing Students.

For computer science students, the world of software might seem all-encompassing. But the programs you write rely on a hidden world of hardware, and understanding that world can be incredibly empowering. This is where digital system design comes in.What is Digital System Design?Think of your computer as a complex city. Information flows through it like traffic, following specific paths and governed by intricate rules. Digital system design is like studying the blueprints of that city – understanding the building blocks (logic gates), the avenues (combinational circuits), and the traffic contro...
