100 Doors Problem:
There are 100 doors in a row that are all initially closed.
You make 100 passes by the doors.
The first time through, visit every door and  toggle  the door  (if the door is closed,  open it;   if it is open,  close it).
The second time, only visit every 2nd door   (door #2, #4, #6, ...),   and toggle it.
The third time, visit every 3rd door   (door #3, #6, #9, ...), etc,   until you only visit the 100th door.
Task:
Answer the question:   what state are the doors in after the last pass?   Which are open, which are closed?

** To install Golang on Ubuntu 17.xx server **

sudo add-apt-repository ppa:gophers/archive
sudo apt-get update
sudo apt-get install golang-1.9-go
export PATH=$PATH:/usr/lib/go-1.9/bin
go version (To verify its mapped correctly, should see something like: go version go1.9.2 linux/amd64)
* make a directory for your go applications, I use /home/apps/go
export GOPATH=/home/apps/go
(Now from inside your /home/apps/go folder you can start creating your go apps)
