BOJ

Repository of submissions to Baekjoon Online Judge (BOJ) problems.

📚 Reference

Submitted sources are grouped into directories in Codes/, according to the problem number.

• The directory name will be (problem number) / 100 * 100.

Source code for problem #3584 can be found in Codes/3500.

Creating files with make.sh

Use ./make.sh problem_number [file_extension] to create a source file in the correct directory.

• [file_extension] is optional. Defaults values is cpp.

./make.sh 3584 cpp will create Codes/3500/3584.cpp.

🖥️ Compile & Run

The default compile options are:

• -Wall: Show all warnings.
• -std=c++17: Use C++17.

Compile and run submit.cpp

submit.cpp is the file I usually use for writing code. I solve problem on this file first, then move the source after the source is accepted.

To run the file, type ./cmp.sh on the terminal. It will automatically run the following:

g++ submit.cpp -Wall -std=c++17 -o submit && ./submit

Note. This does not support additional compile options for g++.

Compile and run specific source

To execute the source for some particular problem, type the following:

./cmp.sh [PROBLEM_NUMBER] [OPTIONS]

• PROBLEM_NUMBER: Problem number.
• OPTIONS: (Optional) Additional compile options for g++.

Example. To run the code for #1000 with -Werror option, type ./cmp.sh 1000 -Werror.

Note. When compiling a specific source using problem number, -I . has been added so that g++ will look for files in the current directory. Without this option, custom headers don't work and compilation fails.
