问题描述:
给定一个正整数,返回它在 Excel 表中相对应的列名称。
例如,
1 -> A 2 -> B 3 -> C ... 26 -> Z 27 -> AA 28 -> AB ...
示例 1:
输入: 1 输出: "A"
示例 2:
输入: 28 输出: "AB"
示例 3:
输入: 701 输出: "ZY"
方法1:
1 class Solution(object): 2 def convertToTitle(self, n): 3 """ 4 :type n: int 5 :rtype: str 6 """ 7 alph="0ABCDEFGHIJKLMNOPQRSTUVWXYZ" 8 9 quo = 0 10 res="" 11 flag = False 12 while n != 0: 13 quo = n // 26 14 remainder = n % 26 15 n = quo 16 if remainder == 0: 17 res += ("Z") 18 flag = True 19 if quo == 1: 20 break 21 if quo == 27:#除数为702时,商27余0结果为zz 22 res += ("Z") 23 break 24 else: 25 if flag: 26 res += str(alph[remainder-1]) 27 flag = False 28 else: 29 res += str(alph[remainder]) 30 res = res[::-1] 31 return res
官方:chr(65)为A
1 class Solution(object): 2 def convertToTitle(self, n): 3 """ 4 :type n: int 5 :rtype: str 6 """ 7 result = "" 8 while n != 0: 9 result = chr((n-1)%26+65) + result 10 11 n = (n-1)/26 12 return result
