When I started learning DSA, I thought the only way to get better was to solve more and more problems. 100… 200… maybe even 1000. But after a few months, I noticed something. The questions looked different, but the logic behind them was often the same. The same ideas kept coming back, in arrays, trees, graphs, and even DP. That’s when I realized something important: you don’t need to solve thousands of problems. You just need to learn the main patterns that repeat again and again. 👉 5 patterns can cover 500+ array problems. 👉 6 patterns for 400+ tree problems. 👉 8 for 700+ DP problems. 👉 7 for 350+ graph problems. 👉 4 for 400+ string problems. Once you understand these patterns, you stop getting stuck. You start seeing how everything connects. And even new problems start to look familiar. In coding rounds, companies really check only three things: → How fast you find the pattern → How well you optimize → How clearly you explain your logic When you know your patterns, you solve faster, stay calm, and feel confident, no matter how hard the problem looks. Because in the end, DSA is not about solving every problem. It’s about seeing the pattern behind them all. PS: Don’t chase numbers. Chase understanding. That’s what makes you stand out in every interview. #sde #dsa #coding #conections #networking LinkedIn LinkedIn News
