Grokking the Coding Interview Patterns

Solution: Merge Intervals

Explore how to merge overlapping intervals from a list by sorting them and iterating to combine overlaps. Understand the optimized approach that reduces time complexity and produces non-overlapping intervals, helping you solve common interval problems in coding interviews.

We'll cover the following...

Statement

We are given an array of closed intervalsclosedintervals called intervals, where each interval has a start time and an end time and is represented as intervals[i] = [starti, endi]. Your task is to merge all the overlapping intervalsOverlapping intervals are two or more intervals with at least one common point in time. and return an array of the resulting non-overlapping intervals that cover all the intervals in the input.

Constraints:

  • 1≤1 \leq intervals.length ...
