Complete Array Problems & Resources Guide
· 18 min read
Hey everyone! Arrays are the foundation of data structures and algorithms. Every tech interview and competitive programming contest features array problems. I've spent years mastering array techniques, and I want to share a complete roadmap that will take you from basics to advanced patterns.
The key insight: Arrays aren't just about storing data sequentially. They're the building block for understanding space-time tradeoffs, prefix sums, sliding windows, two pointers, and countless optimization techniques. Master arrays, and you've mastered the foundation of algorithmic thinking.
