The Design and Analysis of Algorithms (DAA) course really helped me think more critically about solving problems efficiently. Instead of just writing code that works, I learned how to choose or design algorithms that save time and use memory wisely. We explored different techniques like divide and conquer, greedy methods, dynamic programming, and backtracking, and I got to see how the same problem could have multiple solutions with very different performance.
