In this problem, we assume that intervals that touch are overlapping (eg: [1,5] and [5,10] should be merged into [1, 10]). This video explains the problem of non-overlapping intervals.This problem is based on greedy algorithm.In this problem, we are required to find the minimum number of intervals which we can remove so that the remaining intervals become non overlapping.I have shown all the 3 cases required to solve this problem by using examples.I have also shown the dry run of this algorithm.I have explained the code walk-through at the end of the video.CODE LINK is present below as usual. No more overlapping intervals present. Complexity: O(n log(n)) for sorting, O(n) to run through all records. Repeat the same steps for the remaining intervals after the first How do we check if two intervals overlap? interval. Why do small African island nations perform better than African continental nations, considering democracy and human development? Cookies Drug Meaning.
