<div style="border: 1px solid grey;"><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br></div>```ruby
|
||
|
|
def reverser(s)
|
||
|
|
/(.*) (.*)/ =~ s
|
||
|
|
"#{$2} #{$1}"
|
||
|
|
end
|
||
|

|

|
|
puts reverser("Ruby Programmierer")
|

```

Alternative Lösung:
|
||
|
|
|
||
|
|
```ruby
|
||
|
|
def reverser(s)
|
||
|
|
m = /(.*) (.*)/.match(s)
|
||
|
|
"#{m[2]} #{m[1]}"
|
||
|
|
end
|
||
|
|
|
||
|
|
puts reverser("Ruby Programmierer")
|
||
|
|
```
