Introduction to Computer Science with CS50 - The Most Popular Course on edX

What I Learned in My First CS50 Course ,in this first course, I learned the basics of how computers work and how we can use computer science to solve problems. One of the main ideas was problem-solving: understanding a problem, breaking it down, and finding an efficient solution.

I also learned about algorithms ( black box) , which are step-by-step instructions for solving problems. The course showed us that there are different ways to solve the same problem, but some solutions are much faster and smarter than others.

One important example was binary search , which helps us find information quickly by dividing the book in half each time we throw the half when it's doesn't matter, and we focus on what important and we do like very fast time and we find the result.
i also learn binary system or binary search because I understand how I can do some numbers and how work computer 1, 2, 4, 8, 16, 32, 64, 128 and in every exemple I did , I do correctly and TBH these numbers helped me understand how computers count and how information is stored.

Overall, I learned how to think more logically, how to search efficiently, and how computers use mathematics to solve problems fast.

The lesson was incredibly good and exceeded my expectations in every way. Everything was explained clearly and at a comfortable pace, which made it easy to understand even the more challenging parts. The lesson was well organized, engaging, and kept my attention from start to finish. I especially appreciated how examples were used to explain key points, making the material feel practical and relevant. The instructor was patient, knowledgeable, and encouraging, which created a positive learning environment. I felt motivated and confident throughout the lesson, and I came away with a much better understanding of the topic. Overall, it was a very effective and enjoyable lesson, and I would definitely recommend it to others who want to learn and improve their skills.

CS50 is Harvard's intro to computer science course on edX. It's a popular course covering algorithms, data structures, programming, and security.
