FJNU-1159 Fat Brother’s new way

Posted 2020-09-06

Description

I bet, except Fat Brothers, all of you don’t like strange way to show integers , he is really like this way to showing integers:

1 -> ‘A’

2 -> ‘B’

…….

26 -> ‘Z’

27 -> ‘AA’

28 -> ‘AB’

…….

Unfortunately, Fat Brother’s mathematics is poor, so he needs your help, he will give you some integers, and you must transform it with Fat Brother’s way.

 

Input

Input starts with an integer T(T <= 10000), denoting the number of test case.

For each test case, an integers n(1 <= n <= 2147483647) is given.

 

Output

For each case, output the corresponding string with upper-case letters.

 

Sample Input

Sample Output

#include <iostream>

int main(void)
{
    char opt[20];
    int t, a, i;
    
    cin >> t;
    while (t--)
    {
        cin >> a;
        for (i = -1; a--; a /= 26)
        {
            opt[++i] = ‘A‘ + a % 26;
        }
        while (~i)
        {
            putchar(opt[i--]);
        }
        cout << endl;
    }
    return 0;
