189 Programming Questions and Solutions - Cracking the Coding Interview

Solid exercise book full of different problems to solve based on the topic at hand. The reuse of this book compared to other computer science books is going to be higher since all of the proposed questions are not bounded specifically to a language. The solutions for this book as well as example coding is based around java, however all questions can be answered in multiple languages, and are worded in a way that they can be applied to other questions, as ive used the same code for other prep questions I have received. I definitely recommend this book if you are looking to challenge yourself and improve your own code in a pratical sense
