Determining whether one array contains the contents of another array in ruby

Question

In ruby, how do I test that one array not only has the elements of another array, but contain them in that particular order?

correct_combination = [1, 2, 3, 4, 5         


        

Answer 1

If you want to ignore the order, (as I did when I came across this post), you could use Array.sort and <=> http://ruby-doc.org/core-1.8.7/classes/Array.html#M000316

a = [1, 2, 3, 4, 5]
b = [2, 1, 5, 4, 3]
a.sort <=> b.sort

You then need to check the output value equals 0.
