题解

使用前缀和，但是要注意列表的索引不要超出范围

n = int(input())
A = list(map(int,input().split()))

a = [0] + A
s = [0] * (n+1)

for i in range(1,n+1):
    s[i] = s[i-1] + a[i]

b = []
for i in range(1,n+1):
    if s[i] > s[n] - s[i]:
        b.append(s[i])
    else :
        b.append(s[n]-s[i])

result = min(b)
print(result)

🆗，下班
