Problem Solving Series in C++

About six months ago, I started a problem-solving series in C++ and in arbic. My goal was to create something truly beneficial for anyone eager to learn—real problem-solving content, just like the structured plans offered by paid academies, but completely free so that anyone can start.

We divided the plan into three levels:

Level 1 (C++ Basics + Introduction to Problem Solving)

1. Variables + Data Types
2. Loops
3. Arrays
4. Strings
5. Functions

For each topic, we solved a full sheet of 26 problems on Codeforces.
Thankfully, we have completed Level 1! You can check it out here:
Level 1 — YouTube Playlist
And here’s the detailed plan we are following:
Detailed Plan

Level 2

1. Time & Space Complexity
2. STL
3. Frequency Array
4. Prefix & Partial Sum
5. Binary Search & Two Pointers
6. Bitmask
7. Bitset
8. Number Theory
9. Recursion

Just like in Level 1, we will solve plenty of problems for each topic. Additionally, there will be a dedicated Math playlist since math is crucial in problem-solving, and another playlist where we solve various problems to help you get ready for contests and improve your ranking.

Level 3

1. Introduction to Graphs
2. DFS
3. BFS
4. Dijkstra
5. Dynamic Programming (DP)
6. Segment Tree
7. Hashing

We aim to complete the series as soon as possible.
