Can someone tell me what should be the Expected CF rating of Convex Hulk problem . I am asking this because it's one of the very few problem of Geometry I ever solved and it took a half day of mine .
And also that is This solution (Mine) Hackable ? I used Graham-Scan + Greedy , first made a convex hull of given points let it be S1 , then removed those point and with the left over points and made another Convex Hull let it be S2. Then for each point in S1 found the closest points in S2 and considered three adjacent points of it . And from S1 took mid point of each side . And then used this point to generate the final convex hull . It ran well within the Time Limit.
