Data Structures Basics
Course 1 of 4 in the Data Structures & Algorithms diploma
You start with the C++ review the diploma needs and complexity analysis, then build the core data structures yourself: vectors, singly and doubly linked lists, stacks and queues. The foundation you need to start solving algorithmic problems with confidence.
Senior Vision Engineer, NVIDIA
What you'll learn
- Analyze your code's time and space complexity.
- Build a vector yourself and understand what happens inside it.
- Implement singly and doubly linked lists and their operations.
- Build stacks and queues and use them to solve problems.

Why CSkilled instead of scattered resources?
A comparison between learning from scattered resources and learning from one integrated curriculum.
Scattered resources (YouTube / generic courses / bootcamps)
- Depth and curriculum: Scattered content with no clear order, so you get lost between levels.
- Practice: Few problems, often without explained solutions, and small, incomplete projects.
- Instructor and language: Uneven quality of explanation, and much of it is in English only.
- Support and cost: No guidance, and dollar-priced subscriptions or expensive bootcamps.
What do you get at CSkilled Academy?
- Depth and curriculum: 70 lectures and 90 hours in two versions, Python and C++, explaining the idea before using any ready-made tool.
- Practice and projects: Graded problems with explained solutions, and hands-on projects that bring what you learned together into complete work.
- Instructor and language: Taught in Arabic with English terminology, with six Diplomas taught by Dr. Mostafa Saad, who has taught programming for 20 years and is a Senior Computer Vision Engineer at NVIDIA with a PhD in Computer Vision.
- Support and payment: A support team that answers your questions on WhatsApp, and interest-free installments for up to 6 months.
