题目:
代码:
class Solution:
def reverse(self, x: int) -> int:
s = str(x) # 转为字符串
length = len(s) # 字符串长度
index = length-1 #用作下标索引
string = '' # 新的字符串
if s[0] == '-':
string += s[0]
while index>0:
string += s[index]
index-=1
if int(string) < -pow(2,31):
return 0
return int(string)
else:
while index>=0:
string += s[index]
index-=1
if int(string) > pow(2,31)-1:
return 0
return int(string)
