Problem: Rahul has set upon the quest for a new logo of his company. He has created the following continuous logo:

    /\
   /  \
  / /\ \
 / /  \ \
/ / /\ \ \
  \ \ \/ / /
   \ \  / /
    \ \/ /
     \  /
      \/

However, his sister, Rashi, likes the following discontinuous design more

   /\
  /  \
 / /\ \
/ /  \ \
  \ \  / /
   \ \/ /
    \  /
     \/

The size of a logo is the longest continuous streak of same characters on an arm.

So, size of 1st logo is 5 while that of 2nd one is 4.

Now, he wants to paint both of these logos on a canvas. 

Given an integer N, write a program that outputs these logos for sizes N and N + 1, one below the other.

Please note that Rahul's logo is only valid for odd sizes and Rashi's logo is only valid for even values.

Input Format:

Each file has just one line containing integer N.

Output Format:

Output the two logos, one below the other.

Constraints:

N ≤ 100

Notes:

An exact checker is used, so please make sure that you strictly adhere to the output format and leave no trailing spaces.

Solution (in PYTHON):

Solution:
def logo(n):
    start = 1
    logo = []
    for i in range(n):
        logo.append( (bin(start)[2:].replace('1','/')+
                  bin(start)[2:][::-1].replace('1','\\')).center(n*2).replace('0',' '))
        start = (start << 1) + i % 2
    logo =  logo+map('  {}'.format, map(''.join,zip(*zip(*logo)[::-1]))[::-1])
    return '\n'.join(map(str.rstrip, logo))
N = int(raw_input())
print logo(N)
print logo(N+1)
