Grokking the Coding Interview Patterns in Go

Solution: Merge Intervals

Explore how to solve the merge intervals problem by sorting intervals and iteratively merging overlaps. Learn to implement an optimized approach with O(n log n) time complexity that produces a list of non-overlapping intervals. This lesson helps you build efficient solutions commonly required in coding interviews involving interval manipulation.

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 the overlapping intervalsOverlapping intervals are two or more intervals with at least one common point in time. and return a new output array consisting of only the non-overlapping intervals.

Constraints:

  • 1≤1 \leq intervals.length ...
