Print Numbers Vertically

ruby-talk
1

Hello,
   I am trying to figure out how I can print an array of numbers
vertically. For example

a = [ 1, 24, 546, 1000, 32, 256 ]

output (spaces optional) :

1 2 5 1 3 2
   4 4 0 2 5
       6 0 6
          0

   I need this because I've got a string to display horizontally and I
need to display a position number underneath each character column.
   I have been thinking about how to do this but it gets complicated
quickly. So far Im thinking:

- convert to string
- for each digit place ( start with 1's place go to biggest )
   - for each num
          - if has digit
                 -print digit
           - else
                   print space

  Any help would be appreciated.

The ouput should have each number in its own column.

Second try:

1 2 5 1 3 2
  4 4 0 2 5
    6 0 6
       0

a = [ 1, 24, 546, 1000, 32, 256 ]
height = a.max.to_s.length
a.map do |num|
  num.to_s.ljust(height).split(//)
end.transpose.each do |line|
  puts line.join(" ")
end

Prints:
1 2 5 1 3 2
  4 4 0 2 5
    6 0 6
      0

HTH,
Sebastian
