Graham scan algorithm rust

WebFeb 21, 2024 · This sorting algorithm should be a comparison sort; otherwise, the lower bound may not be valid. Unfortunately, without knowing the sorting algorithm, it's difficult to point to specific inputs that trigger the worst case. Some sorts, such as quicksort and mergesort, are best-case Θ(n log n). WebGraham's scan algorithm is a method of computing the convex hull of a finite set of points in the plane with time complexity O (n \log n) O(nlogn) .The algorithm finds all vertices of the convex hull ordered along its boundary . The procedure in Graham's scan is as follows: Find the point with the lowest y y coordinate.
