直接整除的256。。运行时间受输入影响极大，三次内竟能超过100%和0.08%的python3代码
ip = input().split('.')
number = eval(input())
add = 0
num = []
for i in ip:
num.append(eval(i))
for j in range(len(num)):
add = add + num[j] * 256**(len(num)-j-1)
print(add)
iplis = []
while(number):
yu = number % 256
iplis.append(yu)
number = number // 256
a = ''
for j in range(len(iplis)):
if j != len(iplis)-1:
a = a + str(iplis[len(iplis)-j-1]) + '.'
else:
a = a + str(iplis[len(iplis)-j-1])
print(a)
