435. Non-overlapping Intervals

Leetcode Solutions

Greedy Approach to Minimize Overlapping Intervals

  1. Sort the intervals by their end times in ascending order.
  2. Initialize count to 0 to keep track of the number of intervals to remove.
  3. Initialize end to the smallest possible integer value to represent the end time of the last added interval.
  4. Iterate through the sorted intervals. a. If the current interval's start time is at least end, update end to the current interval's end time. b. If the current interval's start time is less than end, increment count as this interval overlaps and needs to be removed.
  5. Return count as the minimum number of intervals to remove.
