Draw the lambda blazon To celebrate the 2497th anniversary of the Greek victory at Salamis in 480 BC. Draw the lambda blazon.

The lambda blazon was the lambda painted on greek shields like so:



Puzzle: Given a positive odd integer n, produce an ascii art image of the above shield.

Specifications: 

n=1:

( /\ )


n=3:

(   /\   )
|  /  \  | 
( /    \ )


n=5

(     /\     )
|    /  \    |
|   /    \   |
|  /      \  |
( /        \ )


Graph:

                 x-axis


Description:

There should be exactly n \ characters and n / characters. The /s and \s should not touch the edge of the shield. The bottom and top corners of the shield will be denoted with a ( or ) unless n=1 where there will be one ) and one (. There will always be one space between the bottom corners and the lambda, increasing by 1 with the y axis until y + 1 == n. Non corners of the shield side will be denoted with |. There is no shield top.

          ↗Ｎ      // Print n '/'s towards the upper right corner.
            ‖Ｍ    // Mirror the left half to produce the right half.
