Grokking the Coding Interview Patterns in C#

Solution: Find Right Interval

Explore how to find the right interval for each given interval using two min heaps. Understand the process of maintaining start and end heaps to identify the smallest valid start time efficiently. This lesson helps you implement a time-optimized algorithm with clear steps and grasp its O(n log n) complexity, preparing you for interview questions on interval and heap patterns.

We'll cover the following...

Statement

You are given an array of intervals where each interval is represented by a pair [starti,endi][start_i, end_i]. The startistart_i values are unique, meaning no two intervals begin at the same time.

The task is to find the right interval for each interval in the list. The right interval for an interval ii is an interval jj such that startj>=endistart_j >= end_i ...
