Have you ever heard of Maslow’s hammer, aka the law of the instrument? It’s a conjecture, driven by observation, about how people who only know one way to do things tend to apply what they know to all kinds of different situations.
If your tool belt only has a hammer, you will be tempted to treat everything as a nail. If you only know how to sort a list, you will be tempted to sort your tasks list every time you add a new task or have to pick the next one to tackle, and you will never be able to leverage the context to find more efficient solutions.
The purpose of this book is to give you many tools you can use when approaching a problem. We will build upon the basic algorithms normally presented in a computer science 101 course (or the like) and introduce you to more advanced material.
