Merge Intervals
Explore how to merge overlapping intervals in an array by identifying common time points and returning non-overlapping intervals. Understand the problem constraints and practice implementing solutions to efficiently handle interval merging. This lesson helps you master a fundamental pattern crucial for coding interviews involving scheduling, intersections, and interval management.
We'll cover the following...
Statement
We are given an array of 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
Constraints:
intervals.lengthintervals[i].lengthstartiendi
Examples
Understand the problem
Let’s take a moment to make sure you’ve correctly understood the problem. The quiz below helps you check if you’re solving the correct problem:
Merge Intervals
Given the intervals below, what is the correct output after merging the overlapping intervals?
[ [1, 6], [2, 4] ]
[ [2, 4] ]
[ [1, 6] ]
[ [1, 6], [2, 4] ]
[ [2, 4], [1, 6] ]
Figure it out
We have a game for you to play. Rearrange the logical building blocks to develop a clearer understanding of how to solve this problem.
Try it yourself
Implement your solution in the following coding playground.
std::vector<std::vector<int>> MergeIntervals(std::vector<std::vector<int>> &intervals){// Replace this placeholder return statement with your codereturn {{}};}
