My IMPRINT Experience

Luiz F. Mendes

Computer Science Major

Urbana, IL


Background l.jpg

Background

  • I was born in Brazil in 1986, but my family moved to the United States in 1990.

  • We have been living in Urbana, where I attended King Elementary School, Urbana Middle School, and Urbana High School.


Hobbies and interests l.jpg

Hobbies and Interests

  • Soccer (playing or watching)

  • Basketball – specially college basketball

  • Music

  • Movies

  • Chess

  • Math


The class cs 125 l.jpg

The Class – CS 125

  • “Introduction to Computer Science”

  • Basic programming in the Java language, how to use UNIX, and basic principles of computer science such as recursion, algorithm design, and sorting algorithms.


The internship l.jpg

The Internship

  • Prof. Lenny Pitt and Prof. Cinda Heeren

  • Goal: Developing an interactive and fun way for children in the K-12 level to learn basic concepts of computer science.


The solution l.jpg

The Solution

  • Logic Hunt

  • A game similar to Tetris, but the goal here is to form true logical expressions. Gives students a new way to learn propositional logic.


About logic hunt l.jpg

About Logic Hunt

  • Programmed in Flash using ActionScript (the programming language for Flash)

  • ActionScript is very object-oriented, much like C++ and Java.


Closer look at the code recursion l.jpg

Closer Look At the Code - Recursion

  • One of the important steps of the program is to be able to find the largest legal expression that each block is a part of and create an array (collection of cells, very useful programming tool) with that expression.

  • This is done through recursion.

    (explanation)


Recursion continued l.jpg

Recursion (continued)

  • How the process works:

    • Find the biggest logical expression to the left of the given block through recursion

    • Find the biggest logical expression to the right of the given block through recursion

    • Merge them together into one single logical expression


Stacking blocks l.jpg

Stacking Blocks

  • Array to keep track of how far down a block can fall in each column.

  • Each time a block falls in a particular column, the array entry representing that column will be modified.

  • Variable to keep track of which column the block is currently on.


Classes and inheritance l.jpg

Classes and Inheritance

  • Block

    • ValBlock

      • TBlock

      • FBlock

    • OpBlock

      • AndBlock

      • OrBlock

      • ImpliesBlock

      • BiImpliesBlock
