A palindrome is a string that reads the same forwards as backwards. Using

only a fixed number of stacks and queues, the stack and queue ADT functions, and a fixed

number of int and char variables, write a code to determine if a string is a palindrome. Assume that the string is read from standard input one character at a time. The code should output true or false as appropriate.

Create a class named TIME that has hours, minutes, and seconds, data members, as integers. The class has gettime () to get the specified value in the object, showtime () to display the time object in *hh:mm:ss* format. Write a main () function to create two-time objects. get the value in two objects and display all time objects.

Create a class named Distance that has feets (as int) and inches (as float). The class has Getdist (int, float) to get the specified value in object, Showdist () to display distance object in feets’ inches” format. Write main () function to create two distance objects. Get the value in two objects and display all objects.

Gary Rosenberg has a personal injury protection policy that covers each person in , on, around, or under his car for medical expenses as a result of an accident.

A race is going to be held soon in college. Each racer will be assigned 3 random points from a set of N distinct points, the ith point is denoted by (Xi,Yi). In order to complete the race, each person has to run on a triangular track, assuming the 3 assigned points to be the corners of the track.

Raghav being the lazy participant wanted to run on the track with the least distance among all the possible tracks. Now, he wants your help to find out what is the smallest distance he has to run in order to finish the race.


Input

The first line contains an integer N(3≤N≤100)

N(3≤N≤100) — the number of points.

This is followed by N lines, each containing two integer Xi and Yi (−10^9≤Xi,Yi≤10^9)

— the coordinates of the ith point.


Output

Print a single real number d where d is the perimeter of the smallest track.
