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;
    }

}
