Leetcode Problem 1610. Maximum Number of Visible Points

1610. Maximum Number of Visible Points

Leetcode Solutions

Sliding Window with Angle Normalization

  1. Initialize a list to store angles and a variable to count points at the observer's location.
  2. Iterate over each point:
    • Calculate the angle between the point and the observer's location.
    • If the point is at the observer's location, increment the count.
    • Otherwise, add the angle to the list.
  3. Sort the list of angles.
  4. Duplicate the list and add 360 degrees to each angle in the second half to simulate a circular array.
  5. Use a sliding window to find the maximum number of points within the angle of view.
  6. Return the sum of the maximum points found and the count of points at the observer's location.
