Grokking the Coding Interview Patterns in Python

Solution: Insert Interval

Explore how to insert a new interval into a sorted, non-overlapping list of intervals and merge overlaps through a single-pass solution. Learn to apply interval patterns for efficient problem solving with an O(n) time complexity, improving your coding interview skills on interval-based questions.

We'll cover the following...

Statement

You are given a list of non-overlapping intervals, intervals, where each interval is represented as [starti, endi] and the list is sorted in ascending order by the start of each interval (starti). You are also given another interval, new_interval = [start, end].

Your task is to insert new_interval into the list of intervals such that the list remains sorted by starting times and still contains no overlapping intervalsOverlapping intervals are two or more intervals with at least one common point in time.. If any intervals overlap after the insertion, merge them accordingly.

Return the updated list of intervals.

Note: You don’t need to modify intervals in place. You can make a new array and return it.
