An Array of Arrays using Array.sort_by

[Tom Eaton]

Hi,

I have:

myarray = Array.new
mylist = [1,2]
mylist2 = [3,1]
mylist3 = [2,1]
myarray.push(mylist)
myarray.push(mylist2)
myarray.push(mylist3)
myarray.sort
myarray.each do |x|
puts x[0]
end

And I would like to be able to sort myarray by the first or second
elements in the mylists...

I have been on this problem for a few hours, ay help would be
appreciated.

I have:

myarray = Array.new
mylist = [1,2]
mylist2 = [3,1]
mylist3 = [2,1]
myarray.push(mylist)
myarray.push(mylist2)
myarray.push(mylist3)

You can make your life a bit easier by doing

myarray = [
[1,2],
[3,1],
[2,1],
]

myarray.sort
myarray.each do |x|
puts x[0]
end

And I would like to be able to sort myarray by the first or second

No. ;-) Rather, please post your solution so others can benefit once
they search through the archive.

Kind regards
