55
1. Write code in the corresponding `src/` file for each programming task.
6-
2. Do not change file names — tests depend on them.
7-
3. Commit and push your changes to GitHub.
6+
2. Upload a `PDF` containing all answers with output screenshot in the docs/ folder
7+
- You can create a doc and convert it to PDF online.
8+
- Name pdf as `answer.pdf`
9+
- Your first line of pdf should be `Name: Firstname-Lastname`. Eg: Name: Nirajan-Thakuri
