# Crypto Square

Implement the classic method for composing secret messages called a square code.

Given an English text, output the encoded version of that text.

First, the input is normalized: the spaces and punctuation are removed from the English text and the message is downcased.

Then, the normalized characters are broken into rows. These rows can be regarded as forming a rectangle when printed with intervening newlines.

For example, the sentence

If man was meant to stay on the ground, god would have given us roots.

is normalized to:

ifmanwasmeanttostayonthegroundgodwouldhavegivenusroots

The plaintext should be organized in to a rectangle. The size of the rectangle (`r x c`) should be decided by the length of the message, such that `c >= r` and `c - r <= 1`, where `c` is the number of columns and `r` is the number of rows.

Our normalized text is 54 characters long, dictating a rectangle with `c = 8` and `r = 7`:

 ```1 2 3 4 5 6 7``` ```ifmanwas meanttos tayonthe groundgo dwouldha vegivenu sroots ```

The coded message is obtained by reading down the columns going left to right.

The message above is coded as:

 `1` ```imtgdvsfearwermayoogoanouuiontnnlvtwttddesaohghnsseoau ```

Output the encoded text in chunks. Phrases that fill perfect rectangles `(r X c)` should be output `c` chunks of `r` length, separated by spaces. Phrases that do not fill perfect rectangles will have `n` empty spaces. Those spaces should be distributed evenly, added to the end of the last `n` chunks.

 `1` ```imtgdvs fearwer mayoogo anouuio ntnnlvt wttddes aohghn sseoau ```

Notice that were we to stack these, we could visually decode the cyphertext back in to the original message:

 ```1 2 3 4 5 6 7 8``` ```imtgdvs fearwer mayoogo anouuio ntnnlvt wttddes aohghn sseoau ```

### Submitting Exercises

Note that, when trying to submit an exercise, make sure you're exercise file you're submitting is in the `exercism/vbnet/<exerciseName>` directory.

For example, if you're submitting `bob.vb` for the Bob exercise, the submit command would be something like `exercism submit <path_to_exercism_dir>/vbnet/bob/bob.vb`.
