Problem

The symbol of Jeonbuk National University represents balance and harmony, and a direction and goal toward intellect and ideals. It expresses restrained Korean beauty through unadorned simplicity and empty space. Depending on its orientation, the symbol carries the meanings of a Korean university, a university devoted to scholarship, and a university moving toward the future, and it stands for the philosophy and vision of "Jeonbuk National University, moving beyond growth toward maturity".

Given an integer $N$ , write a program that draws the Jeonbuk National University symbol of width $N$ using the * character.

Input

The first line contains an integer $N$ ( $3 \le N \le 50$ ).

Output

If $N$ is odd, print the Jeonbuk National University symbol of width $N$ made of *. Let $h = (N-1)/2$ . The symbol has $h+2$ lines:

The first line is $N$ copies of *.
The second line is $h$ spaces followed by one *.
Then, for each $i = 1, 2, \ldots, h$ , print one line consisting of $h-i$ spaces, a *, $2i-1$ spaces, and a *.

Do not print any spaces after the last * of a line.

If $N$ is even, print I LOVE CBNU.
