C++ 算法：将数字转换为 Excel 列标题

#include #include using namespace std;

string convertToColumnTitle(int n) { string columnTitle = ""; while (n > 0) { int remainder = (n - 1) % 26; columnTitle = char('A' + remainder) + columnTitle; n = (n - 1) / 26; } return columnTitle; }

int main() { int n; cin >> n; string columnTitle = convertToColumnTitle(n); cout << columnTitle << endl; return 0; }
