# Your program should take as input the height H of the bow tie, where H is an odd positive integer greater than or equal to 5.
# A bow tie with H rows (and 2H columns) should then be printed using the pattern shown below. You may assume that all input data will be valid.

# input = 5

#  *        *
#  ***    ***
#  **********
#  ***    ***
#  *        *

# input = 7

#  *            *
#  ***        ***
#  *****    *****
#  **************
#  *****    *****
#  ***        ***
