How to mix words / change order with regex?

[me_suzy]

hello. I want to mix many words from a text file.

Suppose I have this words: Word_A WORD_B WORD_C WORD_D WORD_E

I want to change something like this: WORD_E WORD_C WORD_B WORD_E Word_A

Any suggestion?

You could probably use capture groups for that.
