How do prevent to delete the Records only Owner or Creater of the Record in Salesforce?

If object model is public and delete button is enabled to pagelayout, but Owner or Contact only to delete the contacts records.
not possible with the help of validation rules so its achievable with the help of Apex Trigger not allow to delete the contacts records otherthan from Users who are not Owner or Creater of the Record.

Apex Trigger in Contact Object:
trigger ContactTrigger on Contact (before delete) {
if(trigger.isBefore){
if(trigger.isDelete){
for(Contact C : trigger.old){
if(!(C.OwnerID == UserInfo.getUserId() || C.CreatedById == UserInfo.getUserId())){
C.adderror(‘You can only delete the record which is Owned or Created by you.’);
}
}
}
}
}
