# HackerEarth Rahuls Logo problem solution

In this HackerEarth Rahul's Logo problem solution 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 the same characters on an arm. So, the 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.
