How can I extract the last shortest string using regex in java

how can i extract the selected range row below

line:

• hello world blah -d blah vlaah -n blah vlahh
• hello world blah -n blah vlahh -d blah vlaah
• hello world blah -d blaaah

I tried. -[dn] .*$

but it found the longest match string as shown below

• hello world blah -d blah vlaah -n blah vlahh

I want to extract the shortest match string. thank you in advance
