# Pizza, Pizza, Deep Dish Pizza!

April 5th is National Deep DIsh Pizza Day, the theme of this challenge. Given a positive integer n (n is greater than 0), create an ASCII deep dish pizza. Actual deep dish pizza shown:

As you can see, there is a layer of crust on the bottom and surrounding the rest of the pizza.

How to make the pizza

The crust is made of two layers. The first layer will be n tall and n*3 long. Length is the number of characters (including spaces) in the highest line. So given n is 1, the first layer would look like this:

\_/  1 character tall
3 characters long


If n is two:

\    /   2 characters tall
\__/
6 characters long


Now for the second layer of the crust. It will go outside the first, inner crust so therefore, it will be n+2 characters tall and (n*3)+6) characters long. Given n is one:

\       /  3 characters tall
\     /
\___/
9 characters long (3 underscores, 3 slashes on either side)


If n is two:

\          / 4 characters high
\        /
\      /
\____/
12 characters long


You would then match up the two highest pairs of \/ with each other for the inner and outer crust. In n is 1:

\ \   / /
\ \_/ /
\___/


If done correctly, it would look like a V without the tops with a one character difference between each layer. Speaking of tops, the crust will be joined together by a pair of /\, separated by a line of underscores (n*3)+2 long to complete the crust and pizza.

Examples

If n is 1:

/\_____/\
\ \   / /
\ \_/ /
\___/


n is 2:

/\________/\
\ \      / /
\ \    / /
\ \__/ /
\____/


n is 3:

/\___________/\
\ \         / /
\ \       / /
\ \     / /
\ \___/ /
\_____/


Winning Criterion

This is , so the shortest code in bytes wins!

• Something looks off in the inner crust examples. The one for n=1 seems to small, the one for n=2 looks like the inner crust from the final n=1 example, etc... – Adám Apr 6 '17 at 6:13
• Can we use a - instead of a _? – Okx Apr 6 '17 at 8:13
• @Okx No you may not – Anthony Pham Apr 6 '17 at 11:04

This handles the top and bottom two lines of the pizza. The middle is repeated by replacing a string of blanks; the  and ' subsitutions automatically correspond to increasing and decreasing numbers of blanks thus positioning the \ \ and / / appropriately. ## Python 2, 153 151 bytes Try it online n=input() a=' '*n b='_'*n print'/\\__'+b*3+'/\\' i=0 exec"print' '*i+'\ \\\\'+' '*(3*n-2*i)+'/ /';i+=1;"*n print a+'\ \\'+b+'/ /' print a+' \\_'+b+'_/'  -2 bytes by substituting repeated values with variables thanks to @KoishoreRoy • Instead of print' '*=~n+'\\'+'_'*-~n+'_/' can you not write print' '*i+' \\_'+'_'*n+'_/'?

Also I shortended -~n, thanks to your idea – Dead Possum Apr 6 '17 at 9:15 • I wasn't simply changing -~n to i, because I was adding the space.

The one for loop is for the n layers between the very top and the bottom of the inside layer. The repetition of (spaces) and _ is done using arrayfun, with array inputs.

## Explanation

The code first declares an Array a. It then declares w and u having the value of whitespace and underscore respectively. Then, it declares a String variable to hold the value of the crust (which can be computed by /\+(n*3+2 underscores)+/\, as mentioned in the Challenge). After that, with a for loop and a Template Literal, the middle of the pizza is created (with each layer having i whitespaces at the starting and (n+1-i*2)+n+(n-1) whitespaces between \ \ and / /, where i represents the index of for loop). At the last, the bottom most part of the pizza is created ((i whitespaces)+\+(n+2 underscores)+/). All parts are joined together and output(ted).

If for some reason the snippet does not display the ASCII art correctly, have a look here.

Happy Deep Dish Pizza Day to everyone!

t contains the left indent while s contains the inside; its _s are subsituted with spaces on the middle rows. l just exists to avoid some repetition.
