Dressing Up

문제

It is important to keep our computers safe and clean. Some people feel that computers should be well-dressed, also. For this question, you will write a program to print out a bow tie on the computer screen.

Your program should take as input the height $HH$ of the bow tie, where $HH$ is an odd positive integer greater than or equal to 5. A bow tie with $HH$ rows (and $2H2H$ columns) should then be printed using the pattern shown below in the sample output.

입력

One line containing integer $HH$. You may assume that all input data will be valid.
