.htaccess redirect to public folder, exclude subdomain - .htaccess

Question

I have a PHP MVC website, the root needs to be redirected to public folder.
www folder includes:
- app
- public
- subdom/subdomain
subdomain folder is subdomain.website.com
app folder is restricted with Options -Indexes
I need to redirect to public folder, but not if I'm accessing subdomain.
RewriteCond %{THE_REQUEST} /public/([^\s?]*) [NC]
RewriteRule ^ %1 [L,NE,R=302]
RewriteRule ^((?!public/).*)$ public/$1 [L,NC]
This will always get me into public folder but I can't access my subdomain.
I can always either access my subdomain or be redirected to public folder but even when I want to access my subdomain.
This is default .htaccess file in the www folder on Wedos webhosting.
RewriteEngine On
RewriteCond %{REQUEST_URI} !^domains/
RewriteCond %{REQUEST_URI} !^/domains/
RewriteCond %{HTTP_HOST} ^(www\.)?(.*)$
RewriteCond %{DOCUMENT_ROOT}/domains/%2 -d
RewriteRule (.*) domains/%2/$1 [DPI]
RewriteCond %{REQUEST_URI} !^subdom/
RewriteCond %{REQUEST_URI} !^/subdom/
RewriteCond %{HTTP_HOST} ^(www\.)?(.*)\.([^\.]*)\.([^\.]*)$
RewriteCond %{DOCUMENT_ROOT}/subdom/%2 -d
RewriteRule (.*) subdom/%2/$1 [DPI]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^domains/[^/]+/(.+[^/])$ /$1/ [R]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^subdom/[^/]+/(.+[^/])$ /$1/ [R]
How do I exclude subdomains from the redirect?
website.com should be website.com/public
subdomain.website.com should remain that way - it should not be website.com/public
Thanks!

You should add a RewriteCond before 2 rules that deal with /public to check current host name:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^(www\.)?website\.com$ [NC]
RewriteCond %{THE_REQUEST} /public/([^\s?]*) [NC]
RewriteRule ^ %1 [L,NE,R=301]
RewriteCond %{HTTP_HOST} ^(www\.)?website\.com$ [NC]
RewriteRule ^((?!public/).*)$ public/$1 [L,NC]
