📌 CPD Entrance Exam – Practice Guide

The CPD entrance exam is open to 1st, 2nd, and 3rd year students from any department.
All practice problems will be solved on Codeforces.

🔹 1st Year

Focuses on checking your understanding of basic Python programming and simple problem-solving. You just need to know how to read, understand, and implement code correctly.

Topics: Implementation, brute force, easy sorting, basic sets & dictionaries

Ratings: 800

NB: If you don’t know the topic names, don’t worry—just practice 800-rated problems.

🔹 2nd Year
Similar to 1st year, but with slightly harder problems. You are expected to be more comfortable with logic and basic algorithms.

Topics: All 1st year topics but more harder (edited here)

Ratings: 800 – 900

🔹 3rd Year
Tests stronger problem-solving skills and algorithmic thinking. Questions require better optimization and understanding of common techniques.

Topics: All previous topics (1st year & 2nd year) + two pointers, sliding window, prefix sum, matrix problems

Ratings: 800 – 1200 (max)

❓ Have questions or need clarification?
Feel free to drop them in the chat—we’re happy to help.

How to Filter Problems by Rating and Topic on Codeforces ❓

If you’re confused about how to filter problems by rating or topic, follow these steps:

Step 1:
Log in to Codeforces. If you don’t have an account, create one.

Step 2:
Go to the Problemset tab.

Step 3:
On the right side, find the box labeled “Filter Problems.”
Under Difficulty:

-> Enter the minimum rating on the left (for all of you, this is 800).
-> Enter the maximum rating on the right (e.g., 800, 900, or any value).

Step 4:
Click “Add tag” and select the topics mentioned earlier.

📌 Note:

- For 3rd-year students, only the Two Pointers tag is required (this also includes Sliding Window).

- For Prefix Sum and Matrix, try searching on Google like:
“Prefix Sum practice questions on Codeforces”

Step 5:
Click the Apply button to apply your filters.

✅ That’s it!

Additional Notes:

In the problem list, you’ll see a green check icon (✅). Clicking it shows the most commonly solved problems, making practice easier.

📲 Apple May Release a Foldable iPhone

Apple is testing two foldable iPhones:

📖 Book-style Fold – Opens like a book (first expected model)
📱 Flip-style Fold – Small clamshell phone (may come later)

If the first foldable iPhone is successful, Apple may create more foldable designs in the future.

🤔 Is Apple innovating… or just copying others?

❤️ — Innovation
🔥 — Late but smart move
👎 — Just copying

🛑 Spain Plans to Ban Social Media for Under 16

Spain’s Prime Minister says children under 16 should not use social media.
He says today’s internet is like a “digital Wild West” — meaning it can be unsafe for kids.

The government wants social media companies to: • Stop under-16 users from creating accounts
• Use real age verification (not just clicking “I am 16+”)
• Take responsibility for harmful or hateful content

Australia already made a similar law and was the first country to do it.
Now countries like France and others in Europe are also thinking about it.

Some people support this to protect kids.
Others worry it may limit freedom or be hard to enforce.

If this rule came to Ethiopia…

Should social media be banned for students under 16?

❤️ — Yes, it helps protect students
👎 — No, students should learn to use it responsibly

@TechwithhosBot

I personally love learning from Angela Yu, especially for full-stack and Python. Her explanations are very clear and practical.

For software and development basics, I really like Programming with Mosh.

For clean coding tutorials, Bro Code is simple and beginner-friendly.

For deep understanding and tech analysis, Alex The Analyst is great.

And for problem solving and interview prep, I really enjoy NeetCode — super helpful for DSA and coding interviews.

These are some of my favorite YouTube resources that helped me grow in tech.
