What are DSA patterns and why are they important?

DSA patterns are reusable problem-solving blueprints (like Two Pointers, Sliding Window, or Monotonic Stack) that solve dozens of LeetCode problems. Instead of memorizing hundreds of solutions, mastering ~20 core patterns lets you solve almost any coding interview question.

How many DSA patterns are there for coding interviews?

There are 59+ distinct patterns ranging from fundamentals (Arrays, Two Pointers) to advanced topics (Bitmask DP, Segment Trees, Topological Sort).

Is DSAPatterns suitable for FAANG coding interview prep?

Yes! DSAPatterns provides C++ code templates, interactive visualizations, and 300+ LeetCode problems categorized specifically for FAANG and top tech interviews.

Are code templates provided for every pattern?

Yes. Every pattern cheatsheet includes copy-paste code templates in C++, Python, Java, and JavaScript with step-by-step walkthroughs.
