Reading Textfiles
Hi,
I got a textfile of integers like the one below. 1 2 3 323 4656 22 3 0 When I use f = File.open("file.txt","r") list = f.readlines My array list is populated with strings, that is list = ["1","3"....etc] rather than integers. How do I read the textfile and put actual integers to my array wit elements of the textfile?

You could use map:
Code:
data = File.open(file).readlines.map { |l| l.chomp.to_i }
Of course, you will want to some verification of that input to make sure that you are not trying to convert a word into a numeric value...
