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...
Python字符串内置方法 python字符串内置reverse 前段时间看到letcode上的元音字母字符串反转的题目,今天来研究一下字符串反转的内容。主要有三种方法: 1.切片法(最简洁的一种) #切片法 def reverse1(): s=input("请输入需要反转的内容:") return s[::-1]...
