Hello CODEFORCES.
I have a problem in my code A of last Div.2 contest.
Help!
for _ in range(int(input())):
n=int (input())
l=list(map(int,input().split()))
x=sum(l)
if (x)==n:
print(n-4)
else:
for i in range(n):
if i!=n-1:
if l[i]==-1 and l[i+1]==-1:
x+=4
break
else:
if l[-1]==-1 and l[0]==-1:
x+=4
break
print(x)
Are these.

You had written one more condition. You were thinking l[0] as the next index of l[-1].
