Manipulating two arrays in ruby way

Rails
1

Hi,

I have two arrays:

A = [“a”, “b”, “c”, “d”, …]
B = [“1”, “2”, “3”, “4”, …]

And I need to create new array C

C = [“a$1”, “b$2”, “c$3”, “d$4”, …]

How so I do this in ruby way?

Thanks,

irb> A = (‘a’…‘e’).to_a; B = (1…5).to_a; C = A.zip(B).map {|(a,b)|
“#{a}$#{b}”}
=> [“a$1”, “b$2”, “c$3”, “d$4”, “e$5”]

But you shouldn’t use Capitals unless you intend to create a constant.

Check out the ruby docs for arrays and try it itself.
