# Is there any way to format a string. I.E. I've got a variable 
# which may be 1, 2, 3 and the variable is added to string. I want 
# to show whole string formatted as follows:
#  100
#    1
#   10
# 1100

it would be nice to show original string and it's transformation, 

but anyway, is it like this?

irb(main):092:0> "1 20 333 1000 55".split.each{|x| puts x.rjust(4)}
   1
  20
 333
1000
  55

this is just using #rjust. 

irb(main):093:0> system "qri String#rjust"
----------------------------------------------------------- String#rjust
     str.rjust(integer, padstr=' ')   => new_str
------------------------------------------------------------------------
     If integer is greater than the length of str, returns a new String
     of length integer with str right justified and padded with padstr;
     otherwise, returns str.

        "hello".rjust(4)            #=> "hello"
        "hello".rjust(20)           #=> "               hello"
        "hello".rjust(20, '1234')   #=> "123412341234123hello"

=> true

robert already gave a handful of other hints.
