+# Codeforces Users Submissions Dataset (End of 2024)
+
+This project provides the usersCodeforcesSubmissionsEnd2024.csv file, containing anonymized submission data of approximately 15,000 active Codeforces users. The dataset includes all submissions from the inception of Codeforces up to the end of November 2024. It is designed to support AI and data-driven projects. (All data was collected using the open Codeforces API)
+## Dataset Overview
+
+The file contains **17,607,999 rows** with the following columns:
+
+- **`handle`**: An anonymized and shuffled user nickname (e.g., `user{i}`).
+- **`rating_at_submission`**: User's rating at the time of submission.
+- **`problem_rating`**: Problem difficulty rating.
+- **`id_of_submission_task`**: Unique problem identifier on Codeforces.
+- **`verdict`**: Result of the submission (e.g., `OK`, `WRONG_ANSWER`).
+- **`time`**: Time of submission (in seconds since the Unix epoch).
+
+## Purpose of the Dataset
+
+1. **AI Development**: This dataset can be used to create intelligent systems to enhance user learning on Codeforces.  
+   _(Example: The author of this dataset is currently working on the project "Codeforces User Analysis System for Generating Individual Training Recommendations," which aims to recommend tasks to users based on their weaknesses.)_
+
+2. **Time Saving**: Collecting such data manually can be time-consuming (it took ≈7 hours for this dataset). By providing it in a ready-to-use format, we aim to save your time and effort.
+
+3. **Reduce Server Load**: This dataset minimizes repetitive data scraping, thereby reducing the load on Codeforces servers.

+
+## How to Use
+
+1. Load the dataset using your favorite library (e.g., `pandas` in Python):
+   ```python
+   import pandas as pd
+   df = pd.read_csv("usersCodeforcesSubmissionsEnd2024.csv")
