I tried to add a new user in my international server located in US. Unfortunately I did a mistake by replacing sudoers file in /etc/sudoers. I donot know the root password too.Now, I can not use sudo command so can any one help me to recover my system in previous stage.

No. If you don't have root access, you cannot change /etc/sudoers.
If you used the command "visudo" as you should, there probably is
a backup file. But still, you must have root access. Contact the
sysadmin of the server and ask for root access again.
