Interview Process
The interview consisted of multiple rounds, including a technical assessment focused on algorithmic problem-solving. The format was primarily coding on a whiteboard or an online coding platform, with a duration of approximately one hour for the technical round.
Technical Questions
- GPS Recorder Problem (Geometry)
- You are implementing a GPS recorder that records a sequence of locations while a user is moving. Each location is represented as a 2D point (x, y). The recorder should only save a new point if the movement direction changes. If three consecutive points lie on the same straight line, the middle point is considered redundant and should be removed. Your task is to return the simplified path after removing all redundant points.
- Input: An integer array points, where points = [xi, yi]. The points are ordered by time.
- Output: Return the simplified list of points, in the original order.
- Rules: Always keep the first and last point. A point is redundant if it is consecutive and collinear with its neighbors.
Tips & Insights
