只需要维护常数个额外变量 代码(Python3) class Solution: def sumOfNumberAndReverse(self, num: int) -> bool: # 枚举 [0, num] 内的每个数 for i in range(num + 1): # 如果当前 i 满足题意,则直接返回 true if i + Solution.reverse(i) == num: return True # 此时表明无满足题意的数,直...
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]...
mynumberlist = [1,2,3,4,5,6] newlist = list((reversed(mynumberlist))) print(newlist) # Output # [6, 5, 4, 3, 2, 1] Method 2 – Using the reverse() built-in function reverse()is a built-in function in Python. In this method, we will not create a copy of the list. ...
