Tips and Tricks Session 1

Tips and Tricks Session 1 will cover setting up your workspace for ICPC-like competitions, I/O in Java, and fundamental algebra and arithmetic problems.

Here is the skeleton that you should use for all ICPC-type problems from now through the end of the semester:

package _____;

import java.io.*;
import java.util.Scanner;

/**
 * Problem ____: ________
 */
public class Main {
	public static void main(String[] args) throws IOException {

		// For STDIN, put two stars below.
		// For File In, put one star below.
		/*/

		Scanner scanner = new Scanner(new BufferedReader(new InputStreamReader(System.in)));
		/*/
		Scanner scanner = new Scanner(new BufferedReader(new InputStreamReader(new FileInputStream("_______/sample.in"))));
		/**/

		while (scanner.hasNextInt()) {
			// your solution goes here.
			// Example line: int n = scanner.nextInt();
		}
	}
}

To copy the above code, press the “view source” button in the upper-right corner.

There are four fill-in-the-blanks: the package name, the problem ID, the problem name, and then the package name again (in the FileInputStream line).
