Two k-Convex Polygons

CodeChefRating 2214Open on judge ↗

Given n sticks' lengths, determine whether there is a solution to choose 2k out of them and use these 2k sticks to form two k-convex polygons (non-degenerated), namely, two convex polygons each has exactly k sticks as its sides, and every adjacent sticks are not parallel. Input The first line contains two space-separated integers n and k, denoting the number of sticks and the size of convex po
