汽水瓶---python实现多行输入
def changeWater(cout_0):
# 喝水的瓶数
cout_1=0
if cout_0<2:
return 0
while cout_0>2:
cout_1+=cout_0//3
cout_0=cout_0//3+cout_0%3
if cout_0==2:
cout_1+=1
return cout_1
# 空盖子个数
lines=[]
while True:
try:
# PYTHON多行输入以空格“ ”结束
lines.append(int(input()))
except:
result=[]
for i in lines:
result.append(changeWater(i))
for i in result:
print(i)
break
