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
解题思路：
JAVA实现如下：
static public String convertToTitle(int n) {
StringBuilder sb = new StringBuilder();
while (n > 0) {
int temp=‘A‘+n%26-1;
if(temp<‘A‘)
temp+=26;
sb.insert(0,(char)temp);
n/=26;
if(temp==‘Z‘)
n--;
}
return sb.toString();
}
