This app can be executed in three ways by run main.rb file:

1. Without parameter

   $ ruby main.rb

2. With passing three space-separated integers as parameters. Assume the first Parameter value > second and third parameter values.

   $ ruby main.rb x y z

3. With passing filename with .in format. In this case, assume the file consists of 6 lines.

   • first line contains three space-separated integers denoting values of size of map and user coordinate.
   • next five lines contains two space-separated integers describing driver coordinate.

   $ ruby main.rb filename.in

   Sample file input content:

    12 1 4
    1 3

Nearest driver will be marked with "N" and another driver will be disappear from map preview.

3. View History

   List of user completed trip information which contains driver name, route, and the price. However, the route is only described as a coordinate sequence or array of coordinate from starting point to destination point. Top of the list are the latest completed trip of user.

• User can be use the app many times even if the app still in use.

• When searching nearest driver from user location, this app use euclidean formula.

• Formula for the price is: unit of distance * C$200 (200 compfest dollar). Unit cost can be modified only by the admin. Unit of distance obtained from number of elements in the array of route.

• First line contains driver name
• Second line contains array of route coordinate (x,y)
• Third line contains the price
