Sort an Array of Strings by their Integer Values

Question

Let\'s say I have an unsorted array from 1 to 10, as shown below...

a = ["3", "5", "8", "4", "1", "2",         


        

Answer 1

For the special case (e-commerce price list) you mentioned

a = ["0-10", "11-20", "21-30", "31-40"]

let's add a few more values to this array (as it was mentioned as price list). so

a = ["0-10", "11-20", "120-150", "110-120", "21-30", "31-40"]

we can sort such an array using the following

a.sort.sort_by(&:length)
