Problem Descriptionsky from childhood like strange things, and is born particularly sensitive to the number, an accidental opportunity, he found an interesting four-digit 2992, this number, its decimal number, its four-digit sum of 2+9+9+2=22, its hexadecimal number BB0 , its four-digit sum is also 22, at the same time its 12 binary number means 1894, its four-digit sum is 22, ah ha, really clever ah. Sky is very fond of this four-digit number, because of his discovery, so here we name it as Sky number. But to judge such a number is still a bit of trouble ah, so now please help to judge any decimal four digits, is not the sky number bar.

The input input contains some four-bit positive integers, and if 0, the entry ends.

Output "#n is a sky number if n is sky.", otherwise the output "#n is not a sky numbers." Each result occupies one row. Note: #n表示所读入的n值.

Sample Input299212340
