Program for Expressionless Face Pattern printing

Given the value of n, i.e, number of lines, print the pattern.

Examples :

Input : n = 5
Output :
*_*****_*****_*
**_****_****_**
***_***_***_***
****_**_**_****
*****_*_*_*****

Input : n = 10
Output :
*_**********_**********_*
**_*********_*********_**
***_********_********_***
****_*******_*******_****
*****_******_******_*****
******_*****_*****_******
*******_****_****_*******
********_***_***_********
*********_**_**_*********
**********_*_*_**********
