| 1. Write a command line program that takes an input string, and returns which | |
| character is consecutively repeated the most times. If multiple characters | |
| repeat the same number of time, return all those characters. | |
| For ex: "aaddddffffaa" will return 'f, d' | |
| For ex: "cat dog ___" will return '_' | |
| SOLUTION : | |
| user_input = gets.chomp |
| Net::SSH.start(name, 'user') do |session| | |
| session.exec!('file.rb') | |
| end | |
| file.rb | |

In Rails 4 it is useful to have a 'page loading' indicator when a user clicks a link. This is a simple way to accomplish that without external libraries. Tested on Rails 4 using TurboLinks.
Great Link for Spinning Loader gifs: http://loading.io/
On CSS Page:
.modal {
display: none;
position: fixed;
