user: # Task
Given an array `arr`, find the maximal value of `k` such `a[i] mod k` = `a[j] mod k` for all valid values of i and j.

If it's impossible to find such number (there's an infinite number of `k`s), return `-1` instead.


# Input/Output

`[input]` integer array `arr`

A non-empty array of positive integer.

`2 <= arr.length <= 10`

`1 <= arr[i] <= 100`

`[output]` an integer

The maximum value of `k` or `-1` if there is none.


# Example

For `arr = [1, 2, 3]`, the output should be `1`.

`1` is the only k which satisfies the given conditions.

For `arr = [1, 1, 1]`, the output should be `-1`.

`1 % k = 1` for `any k > 1`, so it's impossible to find the maximum.

For `arr = [5, 2, 8]`, the output should be `3`.

`5 % 3 == 2 % 3 == 8 % 3 == 2`

user: # How many urinals are free?
In men's public toilets with urinals, there is this unwritten rule that you leave at least one urinal free
between you and the next person peeing. 
For example if there are 3 urinals and one person is already peeing in the left one, you will choose the
urinal on the right and not the one in the middle.
That means that a maximum of 3 people can pee at the same time on public toilets with 
5 urinals when following this rule (Only 2 if the first person pees into urinal 2 or 4).

![Imgur Urinals](https://i.imgur.com/imZE6xm.png)

## Your task:
You need to write a function that returns the maximum of free urinals as an integer according to the unwritten rule.

### Input
A String containing 1s and 0s (Example: `10001`) (1 <= Length <= 20)  
A one stands for a taken urinal and a zero for a free one. 

### Examples

`10001` returns 1 (10101)  
`1001` returns 0 (1001)  
`00000` returns 3 (10101)  
`0000` returns 2 (1001)  
`01000` returns 1 (01010 or 01001) 

### Note
When there is already a mistake in the input string (for example `011`), then return `-1`

Have fun and don't pee into the wrong urinal ;)

Answer: {"fn_name": "get_free_urinals", "inputs": [["10001"], ["1001"], ["00000"], ["0000"], ["01000"], ["00010"], ["10000"], ["1"], ["0"], ["10"], ["110"], ["1011000001"]], "outputs": [[1], [0], [3], [2], [1], [1], [2], [0], [1], [0], [-1], [-1]]}
user: ### Background
In classical cryptography, the Hill cipher is a polygraphic substitution cipher based on linear algebra. It was invented by Lester S. Hill in 1929.



### Task


This cipher involves a text key which has to be turned into a matrix and text which needs to be encoded. The text key can be of any perfect square length but for the sake of this kata we will focus on keys of length 4 forming a 2x2 matrix.

To encrypt a message using the hill cipher, first of all you need to convert the text key into a key matrix. To do that you will convert the key row wise into a 2x2 matrix. Then you will substitute the letters with their respective positions on the alphabet: A=0, B=1,C=2 and so on till Z=25. So for example if we get the key text as ```cats```, the key matrix will be:
    
    [[ 2  0]
     [19 18]]
     
Now the next step is to break the text into pairs of two and convert those pairs into 2x1 matrices. If your text has an odd number of letters then just add a Z next to your last letter. Now again convert those letters into their respective position in the alphabet as above. So for example the text ```Hi``` would be converted into:

    [[7]
     [8]]
     
Now we need to [multiply](https://www.mathsisfun.com/algebra/matrix-multiplying.html) the key matrix by the text matrix to get our encrypted matrix and then find out the encrypted matrix [modulo](https://en.wikipedia.org/wiki/Modulo_operation) 26:

    [[ 2  0]  *  [[7]  =  [[14]   =  [[14]  mod 26
     [19 18]]     [8]]     [277]]     [17]]
     
For the final step we just find out the letters at the alphabet position of 14 and 17 which are ```O``` and ```R```. So ```OR``` is our encrypted message for the message ```Hi```


In this kata you will be given a function named ```encrypt``` with the parameters ```text``` and ```key``` and you have to return the encrypted message in all uppercase letters

``` python
encrypt('','azyb') → ''
encrypt('Hi','cats') → 'OR'
encrypt('This is a good day','bbaa') → 'AAAAAAGACAGAYA'
```

Note:
- The text to encrypt will contain characters other than the alphabets, its your job to clean them before converting text to matrices. Spaces also need to be removed
- The text may contain both uppercase and lowercase alphabets. Its your job to standardize them, the encrypted text however should be returned in uppercase letters.
- The key will always contain 4 lowercase alphabet.

Answer: {"fn_name": "encrypt", "inputs": [["", "azyb"], ["hello", "hill"], ["This is a good day", "bbaa"], ["CODEWARS IS GREAT", "wxyz"], ["Five + Seven = Twelve", "math"], ["+-*/ &*%^$", "azyb"]], "outputs": [[""], ["DRJIMN"], ["AAAAAAGACAGAYA"], ["CICQQIIASSDXKSFP"], ["IVSLIGSLAQEECSWR"], [""]]}
user: A spoonerism is a spoken phrase in which the first letters of two of the words are swapped around, often with amusing results.

In its most basic form a spoonerism is a two word phrase in which only the first letters of each word are swapped:

```"not picking" --> "pot nicking"```

Your task is to create a function that takes a string of two words, separated by a space: ```words``` and returns a spoonerism of those words in a string, as in the above example.

NOTE: All input strings will contain only two words.  Spoonerisms can be more complex.  For example, three-word phrases in which the first letters of the first and last words are swapped: ```"pack of lies" --> "lack of pies"``` or more than one letter from a word is swapped: ```"flat battery --> "bat flattery"```
You are NOT expected to account for these, or any other nuances involved in spoonerisms.

user: Write a function that takes an arbitrary number of strings and interlaces them (combines them by alternating characters from each string).

For example `combineStrings('abc', '123')` should return `'a1b2c3'`.

If the strings are different lengths the function should interlace them until each string runs out, continuing to add characters from the remaining strings.

For example `combineStrings('abcd', '123')` should return `'a1b2c3d'`.

The function should take any number of arguments and combine them.

For example `combineStrings('abc', '123', '£$%')` should return `'a1£b2$c3%'`.

**Note: if only one argument is passed return only that string. If no arguments are passed return an empty string.**

user: # Story

You and a group of friends are earning some extra money in the school holidays by re-painting the numbers on people's letterboxes for a small fee.

Since there are 10 of you in the group each person just concentrates on painting one digit! For example, somebody will paint only the ```1```'s, somebody else will paint only the ```2```'s and so on...

But at the end of the day you realise not everybody did the same amount of work.

To avoid any fights you need to distribute the money fairly. That's where this Kata comes in.

# Kata Task

Given the ```start``` and ```end``` letterbox numbers, write a method to return the frequency of all 10 digits painted.

# Example

For ```start``` = 125, and ```end``` = 132

The letterboxes are
* 125 = ```1```, ```2```, ```5```
* 126 = ```1```, ```2```, ```6```
* 127 = ```1```, ```2```, ```7```
* 128 = ```1```, ```2```, ```8```
* 129 = ```1```, ```2```, ```9```
* 130 = ```1```, ```3```, ```0```
* 131 = ```1```, ```3```, ```1```
* 132 = ```1```, ```3```, ```2```

The digit frequencies are 1 x ```0```, 9 x ```1```, 6 x ```2``` etc...

and so the method would return ```[1,9,6,3,0,1,1,1,1,1]```

# Notes

* 0 < ```start``` <= ```end```
* In C, the returned value will be free'd.

user: # A History Lesson

Soundex is an interesting phonetic algorithm developed nearly 100 years ago for indexing names as they are pronounced in English. The goal is for homophones to be encoded to the same representation so that they can be matched despite minor differences in spelling.

Reference: https://en.wikipedia.org/wiki/Soundex



# Preface

I first read about Soundex over 30 years ago. At the time it seemed to me almost  like  A.I. that you could just type in somebody's name the way it sounded and there was still a pretty good chance it could match the correct person record. That was about the same year as the first "Terminator" movie so it was easy for me to put 2 and 2 together and conclude that Arnie must have had some kind of futuristic Soundex chip in his titanium skull helping him to locate ```Serah Coner```... or was it ```Sarh Connor```... or maybe ```Sayra Cunnarr```...

:-)



# Task

In this Kata you will encode strings using a Soundex variation called "American Soundex" using the following (case insensitive) steps:

* Save the first letter. Remove all occurrences of ```h``` and ```w``` except first letter.
* Replace all consonants (include the first letter) with digits as follows:
 * ```b```, ```f```, ```p```, ```v``` = 1
 * ```c```, ```g```, ```j```, ```k```, ```q```, ```s```, ```x```, ```z``` = 2
 * ```d```, ```t``` = 3
 * ```l``` = 4
 * ```m```, ```n``` = 5
 * ```r``` = 6
* Replace all adjacent same digits with one digit.
* Remove all occurrences of ```a```, ```e```, ```i```, ```o```, ```u```, ```y``` except first letter.
* If first symbol is a digit replace it with letter saved on step 1.
* Append 3 zeros if result contains less than 3 digits. Remove all except first letter and 3 digits after it

## Input

A space separated string of one or more names. E.g.

```Sarah Connor```

## Output

Space separated string of equivalent Soundex codes (the first character of each code must be uppercase). E.g.

```S600 C560```

Each letter of a word scores points according to its position in the alphabet: `a = 1, b = 2, c = 3` etc.

You need to return the highest scoring word as a string.

If two words score the same, return the word that appears earliest in the original string.

All letters will be lowercase and all inputs will be valid.
