Related to question Excel Sheet Column Title

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

For example:

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

与Excel Sheet Column Title一样都是26进制的转换 代码如下：

public class Solution {
    public int titleToNumber(String s) {
        if(s.length()==0){
            return 0;
        }
        int res=0;
        for(int i=0;i<s.length();i++){
            res=res*26+(s.charAt(i)-'A'+1);
        }
        return res;
    }
}
