UID and GID in LInux

After removing a user and group in linux, can I reuse a UID and GID.

In case the old directory granted to this UID and GID, does it mean the new user will inherit all the access permission to the files and folders ?

How to list out all the folders which can be accessed by a users ?

How can I ensure any new user will use a new UID / GUID ? Tks
To find files with specific UID ownership.

 #find  / -uid  <UID>

To make it ensure first check the last UID/GID used from /etc/passwd and /etc/group and then while creating use #useradd -u <UID> /// #groupadd -g <GID>
