        //Set<Id,Integer> ownerids=new Set<Id,Integer>();
        
        Set<Id> ownerids=new Set<Id>();
    
//reterving the owner id for the lead
for(Lead l : Trigger.new)
{
        Id ownerId=l.OwnerId;
        ownerids.add(ownerId);
    //User theower1=[SELECT Id, Region__c FROM User where Id = :l.OwnerId];
    //User theowner=[SELECT id,region__c FROM USER WHERE id=l.ownerId];u
}   
List<User> theower1=[SELECT Id, Region__c FROM User where Id IN:ownerids];
Map<Id.User> userownerlead=new Map<Id.User>(theower1);

    
    for(Lead l : Trigger.new)
        l.Region__c=theower1.Region__c;
