Problem

Revision en1, by Pakgamer2022, 2023-02-03 10:14:36

Hello CODEFORCES.
I have a problem in my code A of last Div.2 contest.
Help!

Code

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)

Those who don't Help.

By the way CP is Getting harder and harder by the minute.
I propose to have div 4 contests every week.
