Htaccess redirect from get request?

Question

htaccess

Good afternoon.
Please tell me how to make a redirect from:
site.com/?lang=ru to site.com/ru /
and so that when you go to any page (for example, a category) it would be:
site.com/ru/zhenschinam and not site.com /zhenschinam

Thank you!

immediately to you in any language and any URL

RewriteCond %{QUERY_STRING} (?:^|&)lang\=(.+)(?:$|&)
RewriteRule ^(.*)$ /%1/$1? [L,R=301]
