Come up with a solution as below :

C:\>ruby -00 -e 'a= gets; puts a ;puts "here is: #{$/.inspect}"'
Hi

Hi

here is: "\n\n"

C:\>ruby -015 -e 'a= gets; puts a ;puts "here is: #{$/.inspect}"'
hi
hi
^Z
hi
hi
here is: "\r"

C:\>ruby -011 -e 'a= gets; puts a ;puts "here is: #{$/.inspect}"'
Hello

^Z
Hello

here is: "\t"

C:\>

Query: Couldn't understand how the "\t" and "\r" effecting the CODE 
output. Need help here.
