CodeWarmers!
"Center for CS Education & Outreach presents CodeWarmers, a course providing an enjoyable introduction to programming and algorithms through programming contest problems. Participants should be comfortable with basics of Java, C++, or Python. Logistics include in-person or online attendance at UT Dallas with focus on C++/Java. Recommended Java compilers & IDEs are Java Platform (JDK) and Eclipse. For C++, MS Visual Studio Community Edition is suggested. Explore opportunities like IOI/USACO and ACM ICPC competitions for more challenges."

Center for CS Education & Outreach Center for CS Education & Outreach presents CodeWarmers! Enjoyable introduction to serious programming & algorithms through Programming Contest Problems
Pre-requisites Participants should be comfortable with the basics of programming in Java/C++/Python. Those basic concepts are decisions, loops, functions/methods, and arrays. If you are new to programming, you should complete CS1336 Programming Fundamentals course in UT Dallas, or Java/C++/Python coding camp through our K12 Outreach program, OR should have equivalent experience.
Logistics You can attend this course @ UT Dallas in-person or online. You should bring a laptop with WiFi access to in-person sessions it is limited to UT Dallas sessions. We will solve the weekly problem first, then optionally discusss & solve one more problem if time permits. Then, the next week s problem will be discussed. usaco.org supports C++, Java & Python, but we will focus on C++ / Java in the course, though the most content should be language-independent.
Java compiler & IDE Compiler: Java Platform (JDK) www.oracle.com/technetwork/java/javase/downloads Eclipse IDE for Java Developers www.eclipse.org/downloads/ Simpler jGRASP IDE from jgrasp.org is OK, but NetBeans is not recommended since it requires a package for each project & package fails in compilation @ usaco.org.
C++ compiler & IDE MS Visual Studio Community Edition www.visualstudio.com/products/visual-studio-community-vs (or) codeblocks-13.12mingw-setup.exe from www.codeblocks.org/downloads/26 (or) NetBeans C/C++ bundle from netbeans.org/downloads/ Google for Configuring the NetBeans for C++ and follow steps to install a C++ compiler. (or) www.eclipse.org/downloads/ Eclipse IDE for C/C++ Developers
IOI/USACO International Olympiad in Informatics USA Computing Olympiad (USACO) feeds to it Information & competitions: www.usaco.org USACO training site: train.usaco.org/usacogate We need to create accounts in both sites. Yearly world-level contest for high school students
ACM ICPC More complicated college level problems ACM International Programming Contest Information: icpc.baylor.edu ACM programming competitions training site: uva.onlinejudge.org
ACM ICPC Competitions College level Region level International Competition: ACM-ICPC World Finals every year - icpc.baylor.edu Dr. Ivor Page runs CodeBurners email list with weekly challenge problems Additionally, he conducts monthly contests @ UT Dallas and trains few teams for regional contest too. Dr. Page also runs a High School Programming Contest every semester nearly 100 teams attended in Fall 2015! Details @ utd.edu/k12/contest
More online competition sites www.codechef.com www.topcoder.com www.spoj.com projecteuler.net Lot more at en.wikipedia.org/wiki/Category:Programming_contests
USACO competitions Individual competitor Uses input files & output files (NO standard input/output) Upload and submit the source file for assessment Typically 10 testcases For each case, result can be YES, NO, or Time-over Need to get OK for all testcases Helps you by pointing out invalid output & showing the correct output We will stick to USACO website in this course due to its friendly interface & simpler problems
ICPC competitions team based (each team has 3 college students) Uses input files & output files (NO standard input/output) Varying # of testcases Upload and submit the source file for judging 3 indications: Success, Wrong answer, or Time Exceeded No information on test input/output provided for wrong answers
Start-up code for C++ (training site) /* ID: jeyak71 PROG: beads LANG: C++ */ Needed for USACO training site #include <iostream> #include <fstream> #include <string> using namespace std; int main() { ofstream fout ("beads.out"); ifstream fin ("beads.in"); int x, y; fin >> x; fout << y; fout.close(); }
Start-up code for Java (training site) /* ID: jeyak71 PROG: beads LANG: JAVA */ import java.util.*; import java.io.*; Needed for USACO training site class beads { public static void main(String[] args) throws Exception { Scanner input = new Scanner(new File("beads.in")); PrintWriter output = new PrintWriter("beads.out"); int x = input.nextInt(); output.println( ); output.close(); }
Start-up code for C++ (usaco) #include <iostream> #include <fstream> #include <string> using namespace std; int main() { ofstream fout ( cowfind.out"); ifstream fin ( cowfind.in"); int x, y; //fin >> x; //fout << y; fout.close(); }
Start-up code for Java (usaco) import java.util.*; import java.io.*; class cowfind { public static void main(String[] args) throws Exception { Scanner input = new Scanner(new File( cowfind.in")); PrintWriter output = new PrintWriter( cowfind.out"); //int x = input.nextInt(); //output.println( ); output.close(); }
Problem set for Session #1 USACO site Nov 2012 contest: Find the Cow!
