def reverse(x: int) -> int: # 设置32位整数的上下限 INT_MAX, INT_MIN = 2**31 - 1, -2**31 # 记录符号,正数为1,负数为-1 sign = 1 if x > 0 else -1 x *= sign # 去掉负号进行翻转处理:把正数和负数都当正数来对待 # 翻转数字 reversed_x = 0 while x: reversed_x = reversed_...
Did you notice that the reversed integer might overflow? Assume the input is a 32-bit integer, then the reverse of 1000000003 overflows. How should you handle such cases? For the purpose of this problem, assume that your function returns 0 when the reversed integer overflows. 这是一个数字...
Assume we are dealing with an environment which could only store integers within the 32-bit signed integer range: [−2^31, 2^31 − 1]. For the purpose of this problem, assume that your function returns 0 when the reversed integer overflows. 给出一个 32 位的有符号整数,你需要将这个...
Assume we are dealing with an environment which could only store integers within the 32-bit signed integer range: [−231, 231 − 1]. For the purpose of this problem, assume that your function returns 0 when the reversed integer overflows. 解题思路: 假如:x=1234,y=0 1)y乘以10,x把末...

For the purpose of this problem, assume that your function returns 0 when the reversed integer overflows. 中文 LeetCode 7. 整数反转 给出一个 32 位的有符号整数,你需要将这个整数中每位上的数字进行反转。 示例1: 输入: 123 输出: 321 示例2: 输入: -123 输出: -321 示例3: 输入: 120 输出:...
Assume we are dealing with an environment which could only store integers within the 32-bit signed integer range: [−231, 231 − 1]. For the purpose of this problem, assume that your function returns 0 when the reversed integer overflows. 分析:此题思路较明确,相当于将一个整数逆置,只...
要考虑overflow。Python does not have the overflowing problem as whenever an integer overflows it promotes it to long values, that have arbitrary precision flag = 1 if x < 0: x = -x flag = -1 res = 0 while x != 0: mod = x % 10 ...
