No matter what, the way to learn to program is to write code and rewrite it and see it used and rewrite again. Reading other people's code is invaluable as well.

Realize you won't master data structures until you are working on a real-world problem and discover that a hash is the solution to your performance woes.

I took a computer-science course to fill a prerequisite at Stanford, and I realized that every day was a new problem, and every day you got to think about how to solve something new, how to reason through something new, how to develop an algorithm to solve for something you hadn't worked on before.

First figure out why you want the students to learn the subject and what you want them to know, and the method will result more or less by common sense.

The key to a solid foundation in data structures and algorithms is not an exhaustive survey of every conceivable data structure and its subforms, with memorization of each's Big-O value and amortized cost.

I cannot transfer my abilities to anyone, but I can think of quicker ways with which to help people develop numerical aptitude.

Advise for anybody - enjoy what you are doing, enjoy the process of learning and don't be impatient.

I've been programming computers since elementary school, where they taught us, and I stuck with computer science through high school and college.

The first programming assignment I had in high school was to find the first 100 Fibonacci numbers. Instead, I thought it would be cooler to write a program to get the teacher's password and all the other students' passwords. And the teacher gave me an A and told the class how smart I was.
