# Introduction

A code page maps integer values to a specific character. We can visualize a code page like this:

+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
|   | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | A | B | C | D | E | F |
+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
| 0 | q | w | e | r | t | z | u | i | o | p | a | s | d | f | g | j |
+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
| 1 | k | l | y | x | c | v | b | n | m | Q | W | E | R | T | Z | U |
+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
| 2 | I | O | P | A | S | D | F | G | H | J |   |   |   |   |   |   |
+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+


The rows specify the first digit and the columns the second digit of the hex-number.

# The Challenge

Given a string of 16-255 unique characters, output the corresponding code page using the zero-based index of each character in the string as it's value. The input qwertzuiopasdfgjklyxcvbnmQWERTZUIOPASDFGHJ for example would yield the table above.

• The output has to be in the exact same format as the table above. Only a trailing newline is optional.
• If the input length is not a multiple of 16, you need to start a new row for the remaining characters and leave the unused cells empty (=filled with 3 spaces).
• Each character is placed exactly in the middle of a cell, padded by one space to the left and right.
• The values in the first row and column are given by hex-numbers with the digits 0123456789ABCDEF. Those are padded with one space to the left and right as well. You may choose to use lowercase hex-digits but you need to stick to one.
• The only characters present in the output are hyphens -, pluses +, pipes |, spaces  , the digits for hexadecimal numbers and the characters from the input.
• Any builtins that are related to ASCII-art tables or trivialize the problem in any way are forbidden.
• You may assume that the input consists only of characters of a specific encoding. Please specify if that is the case.
• If your language can only handle ASCII input, you may assume ASCII-only input and repeated characters.

# Rules

Happy Coding!

• Can we use lowercase hex digits? Apr 1, 2016 at 23:59
• @Doorknob Yes, clarified it in the challenge. Apr 2, 2016 at 0:00
• Can we assume the input is ASCII (with possibly repeated characters)? Apr 2, 2016 at 0:05
• @DenkerAffe That would conflict with the word "unique" or with "255" in Given a string of 16-255 unique characters, though... Apr 2, 2016 at 0:07
• @LuisMendo Hmm yea, thats true. Gonna allow that for languages that can only handle ASCII. Apr 2, 2016 at 0:14

Try it here.

• Can you show the transpiled code? Apr 2, 2016 at 0:27
• @CatsAreFluffy Just enable the debug mode in the online interpreter. Apr 2, 2016 at 0:42
• What does the newline do? Apr 2, 2016 at 10:56
• @Adnan Whoops, that was an oversight on my part. Fixed, thanks. Apr 3, 2016 at 14:48
• @KennyLau It prints the first +---+---+---[...]. In Pyth, the newline function prints and returns its argument. Apr 3, 2016 at 14:48

# Python 3.5, 326 355 bytes:

(+29 bytes since if the length of the last row is not a multiple of 16, unused cells should be left empty (although, in my opinion, it looks much better if those empty cells are just not even shown))

def f(r):o=' 0123456789ABCDEF';r=[r[0+i:16+i]for i in range(0,len(r),16)];print('+---'*17+'+\n|',end='');[print(' {} |'.format(h),end='')for h in o];print(''.join([str(e+' | ')if e.isdigit()or e.isalpha()else str(e)for e in''.join([str('\n'+'+---'*17+'+\n| '+x[0]+x[1])for x in zip(o[1::1],r)])]),end='');print('  |'+'   |'*(15-len(r[-1]))+'\n'+'+---'*17+'+')


Works like a charm!

Sample Inputs and Outputs:

Input: 'hopper'

Output:

+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
|   | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | A | B | C | D | E | F |

| 0 | h | o | p | p | e | r |   |   |   |   |   |   |   |   |   |   |
+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+

Input: 'honkhonkhonkhonkhonk'

Output:

+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
|   | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | A | B | C | D | E | F |
+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
| 0 | h | o | n | k | h | o | n | k | h | o | n | k | h | o | n | k |
+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
| 1 | h | o | n | k |   |   |   |   |   |   |   |   |   |   |   |   |
+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+

Input: 'hi'

Output:

+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
|   | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | A | B | C | D | E | F |
+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
| 0 | h | i |   |   |   |   |   |   |   |   |   |   |   |   |   |   |
+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+


I hope this is okay.

Also, here is another version I created for this challenge, which, although is an invalid candidate since it does not print out extra empty cells for the last row if its length is not a multiple 16, in my opinion outputs a much better looking page than the one required by OP, mainly because it does not even show empty cells if the last row is not a multiple of 16, but instead just shows filled cells, and that's it:

def f2(r):o=' 0123456789ABCDEF';r=[r[0+i:16+i]for i in range(0,len(r),16)];print('+---'*17+'+\n|',end='');[print(' {} |'.format(h),end='')for h in o];print(''.join([str(e+' | ')if e.isdigit()or e.isalpha()else str(e)for e in''.join([str('\n'+'+---'*17+'+\n| '+x[0]+x[1])for x in zip(o[1::1],r)])]));print('+---'*(len(r[-1])+1)+'+')


Here is a sample input and output for the inapplicable code above:

Input: 'ggreuuobgugoubgoubguorgoruguor'

Output:

+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
|   | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | A | B | C | D | E | F |
+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
| 0 | g | g | r | e | u | u | o | b | g | u | g | o | u | b | g | o |
+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
| 1 | u | b | g | u | o | r | g | o | r | u | g | u | o | r |
+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+

(As you can see, there are no empty cells shown in the entire table. This looks much better to me.)

• "If the input length is not a multiple of 16, you need to start a new row for the remaining characters and leave the unused cells empty (=filled with 3 spaces)." Apr 3, 2016 at 7:24
• @KennyLau Ah, yes. I did not see that. Dang...edit now in progress. Honestly though, this looks much better than the one OP shows, don't you think? Apr 3, 2016 at 7:25
• Why the down vote? Apr 5, 2016 at 19:06
• @R.Kap I couldn't quite tell you, but here, have an upvote

# Excel VBA, 157 146 Bytes (Cheating?)

Anonymous VBE Immediate Window function that destructively takes input from range [A1] and outputs to the ActiveSheet object.

### Golfed

the generated output is

• probs not valid, but cool anyway. To make it more similar (but still invalid?) you should turn on the appropriate cell boarders. Jan 21, 2018 at 14:43
