Now the author properly presents each one of the principle and tries to explain it with a code example (even though the code examples are quite obvious, it helps to learn and confirm where the principle can be applied).  While learning how to code, throughout my entire computer science major I had the privilege to attend classes where the teacher was doing some live coding. There, we knew how the process of turning an algorithm into code was. I remembered that teacher Roberto Martínez always warned us about first designing a clear and accurate solution and not jump straight ahead to code. That is the differenc
