1. Center for CS Education & Outreach
presents
CodeWarmers! Enjoyable introduction to serious programming & algorithms through Programming Contest Problems

2. 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.

3. Logistics
You can attend this 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.

4. Java compiler & IDE Compiler: Java Platform (JDK)
Eclipse IDE for Java Developers
Simpler jGRASP IDE from jgrasp.org is OK, but
NetBeans is not recommended since it requires a package for each project & package fails in usaco.org.

5. C++ compiler & IDE MS Visual Studio Community Edition
(or)
codeblocks-13.12mingw-setup.exe from
NetBeans C/C++ bundle from
netbeans.org/downloads/
Google for “Configuring the NetBeans for C++” and follow steps to install a C++ compiler.
Eclipse IDE for C/C++ Developers

6. IOI/USACO International Olympiad in Informatics
USA Computing Olympiad (USACO) feeds to it
Information & competitions:
USACO training site: train.usaco.org/usacogate We need to create accounts in both sites.
Yearly world-level contest for high school students

7. ACM ICPC More complicated college level problems
ACM International Programming Contest Information: icpc.baylor.edu
ACM programming competitions training site: uva.onlinejudge.org

8. ACM ICPC Competitions College level Region level
International Competition: ACM-ICPC World Finals every year - icpc.baylor.edu
Dr. Ivor Page runs CodeBurners list with weekly challenge problems – Additionally, he conducts monthly 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! utd.edu/k12/contest

9. More online competition sites
projecteuler.net
Lot more at
en.wikipedia.org/wiki/Category:Programming_contests

10. 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

11. 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

12. Start-up code for C++ (training site)
/* ID: jeyak71 Needed for USACO training site PROG: beads LANG: C++ */ #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(); }

13. Start-up code for Java (training site)
/* ID: jeyak71 Needed for USACO training site PROG: beads LANG: JAVA */ import java.util.*; import java.io.*; 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(); }

14. 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(); }

15. 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(); }
