 When I try to authorize ORG from vs code. getting this exception
User-added image

how to avoid for loop in for loop here

for(account a: accounts){ 
                string[] perCamps = a.Campaign_new__pc.split(';');
                for(integer i=0; i<perCamps.size(); i++){
                    if(!conIdByCamName.containsKey(perCamps[i]))
                        conIdByCamName.put(perCamps[i], new list<string>{a.PersonContactId});
                    else conIdByCamName.get(perCamps[i]).add(a.PersonContactId);
                }

here "Campaign_new__pc" is Multi select Picklist field.
I wrote a test for the trigger, which is covering all its dependency classes(apex cls, Schedule). so do I need to write separate test classes for each dependency cls as well? 
hey, I need a small help. I'm working on a lead duplication trigger. there I need to fetch all the existing person accounts and leads to check duplicate. but I have 69k records in-person account. it will through soql exception. so how can I achieve this? I need to show error message on duplication

         incomingMail.RelatedToId = cEvent.id;
         insert incomingMail ;       
        
    }
}

here I'm not testing integration directly, but it was like whenever contact is created it happens, so its making callout indirectly that's why I have to use more class. 

here when I run the test I'm getting error:

System.CalloutException: You have uncommitted work pending. Please commit or rollback before calling out

and when I remove emailmessage record insertion part its working. but I need that

here it is the error im getting when deploying:

I created connected app. So now to the client what I need to provide Just consumer id, consumer secret  is enough
or I need to provide access toKen too, or provide url with acces token and sobject to access , I'm confused here, how we do in real time project's. 
I am confused by fallowing Sobject statement 
'Account a = (Account)s' .  Could you explain it? 
I just deployed one object from one org to another through ant tool. now i could see that object thats fine. but the problem is i cannot see the all fields.i know its field level sucurity issue, but i have full access in profile because i am admin. i can go manually to each field and set field level access. but is there any other way. i dont understand one thing admin can do access anything without giving any access particulartly. but why i cannot access those fields automatically.
 If the amount__c > 100. Show error by validation rule. If I update the value from 90 to 120. What happens in before update trigger scenario and after update scenario. is it will show error in both scenario? I think it will show error on both scenarios 
I have created two sandboxes at a time in free 30 days trail edition. But even though I successfully created I cannot login to sandboxes   by username  suffixed with '.Sandbox name' and used production password.

here I'm not testing integration directly, but it was like whenever contact is created it happens, so its making callout indirectly that's why I have to use more class. 

here when I run the test I'm getting error:

and when I remove emailmessage record insertion part its working. but I need that
