## FAMILYP - Family Problems

Asif and Nafisa are very interested in solving puzzles.They always try to give one another puzzles to see who is the best.So ,as usual, one day, Nafisa gave Asif a matrix.

The matrix is as follows

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z A B C ......
B C D E F G H I J K L M N O P Q R S T U V W X Y Z A B C D ......
C D E F G H I J K L M N O P Q R S T U V W X Y Z A B C D E ......
D E F G H I J K L M N O P Q R S T U V W X Y Z A B C D E F .......
.........................................................................................
.
.

Assume that the matrix is very huge(both row and column wise). Nafisa describes a special sequence as a sequence  whose first term is 'A'[element at (0,0)], second term is 'B'[element at  (0,1)],third term is 'B'[element at (1,0)],fourth term is 'C'[element at (2,0)]. Now,she asks Asif to find the nth term of this special sequence. Help Asif To solve the problem.

### Input

There will be multiple test cases with number N(1<=N<=1000000) per line.

### Output

A character ['A'-'Z'] per line for each number N representing the Nth number in the special sequence.

### Example

```Input:3610Output:
TERM 3 IS BTERM 6 IS CTERM 10 IS D```
