balance = 0

save = 0

x = 0

for i in range(1, 13): budget = int(input())

balance += 300

balance -= budget
if balance < 0 and x == 0:
    x = i
    break
b = balance // 100
save += b * 100
c = balance % 100
balance = balance - b * 100

if x != 0:

print(-x)

elif x == 0:

print(balance + save * 1.2)

有没有大佬帮忙看看为什么2,3,5,7,9,10测试点跑不过呀，样例都是对的
