Java-Excel Sheet Column Title

Given a positive integer, return its corresponding column title as appear in an Excel sheet.

For example:

    1 -> A    2 -> B    3 -> C    ...    26 -> Z    27 -> AA    28 -> AB 

本质就是将10进制改成了26进制 但注意的是 从1开始计数 代码如下:

public class Solution {    public String convertToTitle(int n) {        String res="";        while(n>0){        	res=(char)((n-1)%26+'A')+res;        	n=(n-1)/26;  	        }        return res;    }    }
