1272. Remove Interval

Leetcode Solutions

Sweep Line Algorithm - One Pass Solution

  1. Initialize an empty list result to store the final set of intervals.
  2. Iterate over each interval in the intervals list.
  3. For each interval, check if there is no overlap with toBeRemoved. If so, add the interval to result.
  4. If there is an overlap, determine if it is a left overlap, right overlap, or if toBeRemoved is entirely inside the interval.
  5. Based on the type of overlap, modify the current interval or split it into up to two new intervals, and add them to result.
  6. Continue this process for all intervals in the list.
  7. Return the result list, which now contains the set of real numbers with toBeRemoved removed.
