Algorithms will always be the central point of efficient development, and you will use them everywhere. You'll need to use them when writing code, you'll come across them at every coding interview you attend, and they will definitely be part of your daily development work. Even more, they are part of life, and throughout this book, I'll show you some real-world examples of algorithms to help you understand them more easily. What is algorithmic thinking, though? And how do you use it to help you work through a problem? How to Use Algorithmic Thinking For many people, algorithmic thinking is a complete change in their thinking. The concept isn't difficult - it's merely a way of systematically thinking through a problem and finding the solution, much the same way a computer runs.
