The 14 Patterns to Crack Any Coding Interview

Many beginners make the mistake of trying to solve 500+ LeetCode problems by rote memorization. This is inefficient. The secret shared by top engineers is to focus on the underlying patterns. If you understand the "Sliding Window," "Two Pointers," or "Fast & Slow Pointers," you can solve dozens of variations of the same problem type. This item compiles the top 14 coding patterns that appear in 90% of technical interviews. We aren't just listing problems; we are breaking down the logic of when to apply which pattern. For example, if the problem involves a linked list or an array and asks for a specific sum, the Two Pointer method is your first line of defense. Stop grinding blindly and start recognizing the blueprint.
