- LeetCode #171 #860 #717 #237 #13
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
过程十分简单：
string convertToTitle(int n) {
string res;
while(n > 0){
n -- ;
res = char('A' + n % 26) + res;
n /= 26;
}
return res;
}
本质上是一个10进制转26进制的问题。
这个先减一十分重要。
