Given $$$N$$$ points in $$$2D$$$ plane with integer coordinates. Initially you are at a point $$$p1$$$ , visit all remaining $$$n-1$$$ points and come back to $$$p1$$$ . Between two points you move in a straight line joining them . Only constraint is that no two of the lines must intersect .
Constraints:
$$$3 ≤ N ≤ 1000$$$
$$$-1,000,000 ≤ x i , y i ≤ 1,000,000 $$$
