To prepare for coding tests and improve my own skills, I decided to work through Baekjoon algorithm problems in order.

If I just solve them without writing anything down, I'll surely forget how I solved them later, so I'll write posts covering what I understood as I work through each solution.

The rules for these solutions are as follows.

1. As much as possible, proceed in order of problem number.
2. The default language will be JAVA.
3. Explain the underlying principles in as much detail as possible, even to an excessive degree.
4. To each their own.
5. Avoid golfing the code; write it out in a way that's easy to understand, as far as performance allows.
6. Make active use of comments.
7. Every solution must be based on code whose judge result is Accepted!!
8. Write the code presented in each solution so that it can be copied as-is and still solve the algorithm correctly.
9. Leave Myungho Shin as he is.
