将整数转为EXCEL表格列标，实际上就是十进制转26进制
class Solution
{
public:
string convertToTitle(int n)
{
string result ="";
char apha[27]="ABCDEFGHIJKLMNOPQRSTUVWXYZ";
vector <int> v;
int temp = n;
int remain = 0;
int i = 0;
while(temp)
{
remain = temp%26;
//处理26/52这种26倍数的边界
if (remain ==0)
{
remain = 26;
temp -= 1;
}
v.push_back(remain-1);
temp = temp/26;
}
for (i = v.size()-1; i>=0;i--)
{
result += apha[v[i]];
}
return result;
}
};
int main()
{
Solution s;
string result;
int i = 0;
result = s.convertToTitle(53);
cout << result<<endl;
}
