Module 2: Arrays & Memory

Master the most fundamental data structure. Understand how arrays work at the hardware level and learn the patterns used by top-tier engineers.

The Learning Journey

Array Fundamentals

Beginner20 min

Master the bread and butter of data structures: static vs dynamic arrays and memory characteristics.

Memory Layout & Access

Intermediate20 min

Learn how contiguous memory blocks and cache prefetching make arrays the fastest data structure.

Basic Operations

Beginner25 min

Step-by-step visualizations of insertion, deletion, and searching in both static and dynamic arrays.

Array Algorithms

Intermediate30 min

Advanced techniques: Two-pointer, Sliding Window, and Prefix Sum patterns for interview success.

Skills You Will Build

Static vs Dynamic

Know exactly when to use fixed-size vs resizeable arrays.

Hardware Locality

Understand how to write cache-friendly code that runs 100x faster.

Dynamic Resizing

Master the amortized O(1) analysis of growing arrays.

Two-Pointer Strategy

Solve sorted array problems with zero extra memory.

Sliding Window

Handle contiguous sub-array problems in linear time.

Prefix Sums

Optimize range-sum queries from O(n) to O(1).
