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.
