My advice is that you go through some beginners tutorial about Ruby. After that you will know to implement it. Here is your starting code: require 'csv' class ParseCSV def initialize @csv = CSV.read "data.csv" end def test @csv[0] # it's first row end end pc = ParseCSV.new pc.test As you see it's easier to process your data by csv class, since it's in comma separaterd values format. In constructor you initialize @csv variable which is 2 dimensional array. You acces it through indexes. For example to get 1st cell, then you type @csv[0][0]. You get first row by @csv[0]. If you want to go through all rows then you type: @csv.each do |row| 2012/11/28 Jan E. > You can argue all day long about which solution is easier to understand > and better for a beginner.

As you see it's easier to process your data by csv class, since it'= s in comma separaterd values format. In constructor you initialize @csv var= iable which is 2 dimensional array. You acces it through indexes. For examp= le to get 1st cell, then you type @csv[0][0]. You get first row by @csv[0].=

If you want to go through all rows then you type:
=
@csv.each do |row|

You can argue all day long about which solut= ion is easier to understand
and better for a beginner. But personally, I'm more interested in which=
methods *he* knows. If he knows File.readlines, that's fine. Then we ca= n
use it. If he knows File.foreach, that's fine, too.

I know Ruby programmers love endless discussions about the best
solution. But it would be great if maybe this time you could not do that and just help.


@ Ismail:

Please write down everything that you currently have (ideas, code,
whatever). Your code snippet for the smallest number is already useful.
You'll be able to use that later.
