Solution: Range Module

Explore how to implement a Range Module class that manages half-open intervals by adding, removing, and querying ranges. Understand merging overlapping intervals and using binary search to find overlaps efficiently. This lesson helps you create scalable solutions with custom data structures for interval tracking.

We'll cover the following...

Statement

Design a Range Module data structure that effectively tracks ranges of numbers using half-open intervals and allows querying these ranges. A half-open interval [left,right)[left, right) includes all real numbers nn where ...
