As seen in Netflix’s algorithms, these fundamentals allow developers to solve real-world problems like efficient search engines or recommendation systems. Without DSA, even the most innovative code falters under scale: for example, improper data organisation can lead to O(n²) time complexities, crippling applications in high-traffic environments. O(n²) is represented as quadratic time complexity in computer science, indicating that the algorithm’s running time or space requirements grow proportionally to the square of the input size (n). This usually happens with nested loops, where each element in the input is processed against every other element, leading to a significant increase in operations as the input grows.

Career-wise, DSA proficiency is a gatekeeper for FAANG interviews, where 70% of questions test these concepts. Graduates with strong DSA backgrounds command salaries up to $150,000 for entry-level roles, per Glassdoor data. The emphasis on physical and analytical clarity equips students to approach challenges logically, whether optimising supply chain algorithms or fraud detection models.
