Let's say I have an array 

```
arry = ["a","b","c","d","e","f","g"]

```

and I want to get the fourth, second, and seventh element of that array.

Let's say some other function determined which are the needed values and passed me backan array of indices like `[3, 1, 6]`. In most languages I could write this

```
array[3,1,6] #=> ["d","b","g"] (or "dbg"?)

```

or

```
array[3 1 6] #=> ["d","b","g"]

```

But that won't work in Ruby, of course. Is there a simple way to do this in Ruby? The cleanest I can find is something like:

```
[3,1,6].map { |i| array[i] }

```

I really tried to find a duplicate to this question since it seems so basic, but I just couldn't.

This is remarkably easy to do in most languages, so I'm almost assuming I'm just overlooking the remarkably obvious.
