array-techniques

What problem does it solve?

This skill helps developers solve array-pattern problems efficiently by applying core techniques like two pointers, sliding window, and prefix sums to achieve linear-time solutions.

Core Features & Use Cases

• Two Pointers pattern for in-place element removal and sum problems.
• Sliding Window technique for maximum subarray sums, subarray length minimization, and substring challenges.
• Prefix Sum approach for fast range queries and cumulative calculations, including 2D variants.
• Real-world use cases include coding interview practice, data processing optimization, and reusable templates for common array problems.

Quick Start

Provide an array problem and choose a technique (two-pointers, sliding window, or prefix sums) to see a step-by-step pattern solution.
