When hosting our web applications, we often have one public IP
address (i.e., an IP address visible to the outside world)
using which we want to host multiple web apps. For example, one
may wants to host three different web apps respectively for
example1.com, example2.com, and example1.com/images on
the same machine using a single IP address.
How can we do that? Well, the good news is Internet browsers

| * TASK DESCRIPTION | |
| * | |
| * Consider 2 dimensional space, with discreate coordinates | |
| * - a given starting point ex. (0, 0) | |
| * - you allow to move as (x+1, y), (x-1,y), (x, y+1) , (x,y-1) | |
| * - RESTRICTION: you can not step into the point if the absolute number of a coordinates digits are grater than some N | |
| * f.e if N=21 and a point is (59, -79), sum of digits in coordinates os (5 + 9 + 7 + 9) = 30 > 27 (N) | |
| * the point is prohibited | |
| * - you can not step over the points |
