Reversing a numbermeans changing the order of its digits. Forexample, if we reverse the number 124, we get 421. It involves rearranging the digits of the given number from right to left. There are several ways t
解法1:字符串反转 解法2:数学运算(求余)转换 解法3:递归解法 这个题其实是 LeetCode 9 的基础题。可见,LeetCode 的题目编排就是乱来。 不过呢,相对 LeetCode 9,此题存在一些小的细节必须考虑周全。 题目要求看上去很简单,就是把一个整数从右到左翻过来。比如5,翻过来还是5;123,翻过来就是 321;-124,反过...

7. Reverse Integer 题目链接:Reverse Integer 思路: 因为Python中的数字是没有overflow的,即limit取决于电脑的内存。不过题目有额外要求,假设我们只能处理 32-bit signed 的数字区间。 所以需要另外加一个判断。另外,Python内置的int()函数可以把 "001" 转换成数字 1。

Python字符串倒序-7. Reverse Integer 今天做了下LeetCode上面字符串倒序的题目,突然想Python中字符串倒序都有哪些方法,于是网上查了下,居然有这么多种方法: 个人觉得,第二种方法是最容易想到的,因为List中的reverse方法比较常用,做LeetCode题目7. Reverse Integer也用了这种方法,程序耗时65ms...
[Leetcode][python]Reverse Integer/反转整数 题目大意 反转整数123变为321,-123变为-321 注意:在32位整数范围内,并且001要成为1 假设我们的环境只能存储 32 位有符号整数,其数值范围是 [−2^31, 2^31 − 1]。根据这个假设,如果反转后的整数溢出,则返回 0。
