Algorithm Toolbox for Lecture Notes 03

We have, and will, learn some Java syntax this semester. However, what we really want to focus on in this class is algorithm design and problem decomposition. Below is a cheat sheet, in pseudocode, of what we have in our "toolbox" for conceptually solving problems in the abstract language of computers.

Operators (things we can do)

• Variable declaration and assignment (i.e. x = 3 or x = y)
• Mathematical operators: + - * / %

Data (things we can store, read, and modify)

• User input variables (i.e. num1)
• Variables we define (i.e. sum = num1 + num2)
• Constants (i.e. 3 or 3.14 or "3.14 is pi")
