user: Write a function that receives two strings and returns n, where n is equal to the number of characters we should shift the first string forward to match the second.

For instance, take the strings "fatigue" and "tiguefa". In this case, the first string has been rotated 5 characters forward to produce the second string, so 5 would be returned.
If the second string isn't a valid rotation of the first string, the method returns -1. 

Examples:
```
"coffee", "eecoff" => 2
"eecoff", "coffee" => 4
"moose", "Moose" => -1
"isn't", "'tisn" => 2
"Esham", "Esham" => 0
"dog", "god" => -1
```

For Swift, your function should return an Int?. So rather than returning -1 when the second string isn't a valid rotation of the first, return nil.

user: If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.

Finish the solution so that it returns the sum of all the multiples of 3 or 5 **below** the number passed in. 

> Note: If the number is a multiple of **both** 3 and 5, only count it *once*.
> Also, if a number is negative, return 0(for languages that do have them)

user: Jack and Jill are playing a game. They have balls numbered from `0` to `n - 1`. Jack looks the other way and asks Jill to reverse the position of the balls, for instance, to change the order from say, `0,1,2,3` to `3,2,1,0`. He further asks Jill to reverse the position of the balls `n` times, each time starting from one position further to the right, till she reaches the last ball. So, Jill has to reverse the positions of the ball starting from position `0`, then from position `1`, then from position `2` and so on. At the end of the game, Jill will ask Jack to guess the final position of any ball numbered `k`. 

You will be given `2` integers, the first will be `n`(balls numbered from `0` to `n-1`) and the second will be `k`. You will return the position of the ball numbered `k` after the rearrangement.

```Perl
solve(4,1) = 3. The reversals are [0,1,2,3] -> [3,2,1,0] -> [3,0,1,2] -> [3,0,2,1]. => 1 is in position 3.
```

user: Convert DD (decimal degrees) position to DMS (degrees, minutes, seconds).

##### Inputs:
`dd_lat` and `dd_lon` 2 strings representing the latitude and the longitude in degree -i.e. 2 floats included in [-90, 90] and [-180, 180]. Note that latitude 0 is north, longitude 0 is east.

##### Outputs:
A tuple of DMS latitudes formated as follows:
`DDD*mm'ss.sss"C`

With:
- `DDD`: degrees
- `mm`: minutes
- `ss.sss`: seconds rounded to 3 decimals
- `C`: first letter uppercase of the cardinal direction

user: Your Goal is to create a function that takes  two strings, a guess and a phone number. 

Based on the guess, the function should display a portion of the phone number:

    guess_my_number('052', '123-451-2345')
    would return the string: '#2#-#5#-2##5'
    
    or
    
    guess_my_number('142', '123-451-2345')
    would return the string: '12#-4#1-2#4#'
    
Order of the guess string should not matter, and should not have duplicates of the ten digitis 0-9. Guess will never be an empty string or contains any other charachters. The phone number will always bea ten digit number in the format ###-###-####.

The default number of 123-451-2345 should be included, but can be overwriten by a different number if supplied at the time of execution.

user: The purpose of this kata is to work out just how many bottles of duty free whiskey you would have to buy such that the saving over the normal high street price would effectively cover the cost of your holiday. 

You will be given the high street price (normPrice), the duty free discount (discount) and the cost of the holiday. 

For example, if a bottle cost £10 normally and the discount in duty free was 10%, you would save £1 per bottle. If your holiday cost £500, the answer you should return would be 500.

All inputs will be integers. Please return an integer. Round down.

user: In Russia, there is an army-purposed station named UVB-76 or "Buzzer" (see also https://en.wikipedia.org/wiki/UVB-76). Most of time specific "buzz" noise is being broadcasted, but on very rare occasions, the buzzer signal is interrupted and a voice transmission in Russian takes place. Transmitted messages have always the same format like this:

 MDZHB 01 213 SKIF 38 87 23 95 

or: 

 MDZHB 80 516 GANOMATIT 21 23 86 25 

Message format consists of following parts:

 Initial keyword "MDZHB"; 
 Two groups of digits, 2 digits in first and 3 in second ones; 
 Some keyword of arbitrary length consisting only of uppercase letters; 
 Final 4 groups of digits with 2 digits in each group. 

  
Your task is to write a function that can validate the correct UVB-76 message. Function should return "True" if message is in correct format and "False" otherwise.

user: Same as [the original](https://www.codewars.com/kata/simple-fun-number-258-is-divisible-by-6) (same rules, really, go there for example and I strongly recommend completing it first), but with more than one asterisk (but always at least one).

For example, `"*2"` should return `["12", "42", "72"]`.

Similarly, `"*2*"` should return `["024", "120", "126", "222", "228", "324", "420", "426", "522", "528", "624", "720", "726", "822", "828", "924"]`. Order matters and returning the right one is part of the challenge itself, yep!

user: In this Kata, you will be given a string of numbers in sequence and your task will be to return the missing number. If there is no number
missing or there is an error in the sequence, return `-1`.

For example:
```Haskell
missing("123567") = 4 
missing("899091939495") = 92
missing("9899101102") = 100
missing("599600601602") = -1 -- no number missing
missing("8990919395") = -1 -- error in sequence. Both 92 and 94 missing.
```
The sequence will always be in ascending order.

user: We need you to implement a method of receiving commands over a network, processing the information and responding.

Our device will send a single packet to you containing data and an instruction which you must perform before returning your reply.

To keep things simple, we will be passing a single "packet" as a string. 
Each "byte" contained in the packet is represented by 4 chars.



One packet is structured as below:
```
Header  Instruction   Data1    Data2   Footer
------   ------       ------   ------  ------
 H1H1     0F12         0012     0008    F4F4
------   ------       ------   ------  ------

The string received in this case would be - "H1H10F1200120008F4F4"

Instruction: The calculation you should perform, always one of the below.
            0F12 = Addition
            B7A2 = Subtraction
            C3D9 = Multiplication
            FFFF = This instruction code should be used to identify your return value.
``` 
- The Header and Footer are unique identifiers which you must use to form your reply.

- Data1 and Data2 are the decimal representation of the data you should apply your instruction to. _i.e 0109 = 109._

- Your response must include the received header/footer, a "FFFF" instruction code, and the result of your calculation stored in Data1.

- Data2 should be zero'd out to "0000".


```
To give a complete example:

If you receive message "H1H10F1200120008F4F4".
The correct response would be "H1H1FFFF00200000F4F4"

```
In the event that your calculation produces a negative result, the value returned should be "0000", similarily if the value is above 9999 you should return "9999".


Goodluck, I look forward to reading your creative solutions!

user: In recreational mathematics, a [Keith number](https://en.wikipedia.org/wiki/Keith_number) or repfigit number (short for repetitive Fibonacci-like digit) is a number in the following integer sequence:

`14, 19, 28, 47, 61, 75, 197, 742, 1104, 1537, 2208, 2580, 3684, 4788, 7385, 7647, 7909, ...` (sequence A007629 in the OEIS)

Keith numbers were introduced by Mike Keith in 1987. They are computationally very challenging to find, with only about 100 known.

Implement the code to check if the given number is a Keith number. Return the number number of iteration needed to confirm it; otherwise return `false`.

**Note:** 1-digit numbers are **not** Keith numbers by definition


## Examples

```
n = 197      # --> [1, 9, 7]

# calculation           iteration
1 + 9 + 7 = 17         #    1
9 + 7 + 17 = 33        #    2
7 + 17 + 33 = 57       #    3
17 + 33 + 57 = 107     #    4
33 + 57 + 107 = 197    #    5
```
As `197` is the same as the initial number, so it's a Keith number: return `5`


Another example:
```
n = 196

# calculation          iteration
1 + 9 + 6 = 16        #    1
...

`196` is not a Keith number, so return `false`

user: An expression is formed by taking the digits 1 to 9 in numerical order and then inserting into each gap between the numbers either a plus sign or a minus sign or neither.

Your task is to write a method which takes one parameter and returns the **smallest possible number** of plus and minus signs necessary to form such an expression which equals the input.

**Note:** All digits from 1-9 must be used exactly once.

If there is no possible expression that evaluates to the input, then return `null/nil/None`.

~~~if:haskell
`eval :: String -> Int` is available in `Preloaded` for your convenience.
~~~

There are 50 random tests with upper bound of the input = 1000.


## Examples

When the input is 100, you need to return `3`, since that is the minimum number of signs required, because: 123 - 45 - 67 + 89 = 100 (3 operators in total).

More examples:
```
 11  -->  5  #  1 + 2 + 34 + 56 + 7 - 89 = 11
100  -->  3  #  123 - 45 - 67 + 89 = 100
766  -->  4  #  1 - 2 + 34 - 56 + 789 = 766
160  -->  -  #  no solution possible
```

user: I always thought that my old friend John was rather richer than he looked, but I never knew exactly how much money he actually had. One day (as I was plying him with questions) he said:

* "Imagine I have between `m` and `n` Zloty..." (or did he say Quetzal? I can't remember!)
* "If I were to buy **9** cars costing `c` each, I'd only have 1 Zloty (or was it Meticals?) left."
* "And if I were to buy **7** boats at `b` each, I'd only have 2 Ringglets (or was it Zloty?) left."

Could you tell me in each possible case:

1. how much money `f` he could possibly have ?
2. the cost `c` of a car?
3. the cost `b` of a boat?

So, I will have a better idea about his fortune. Note that if `m-n` is big enough, you might have a lot of possible answers. 

Each answer should be given as `["M: f", "B: b", "C: c"]` and all the answers as `[ ["M: f", "B: b", "C: c"], ... ]`. "M" stands for money, "B" for boats, "C" for cars.

**Note:** `m, n, f, b, c` are positive integers, where `0 <= m <= n` or `m >= n >= 0`. `m` and `n` are inclusive.


## Examples:
```
howmuch(1, 100)      => [["M: 37", "B: 5", "C: 4"], ["M: 100", "B: 14", "C: 11"]]
howmuch(1000, 1100)  => [["M: 1045", "B: 149", "C: 116"]]
howmuch(10000, 9950) => [["M: 9991", "B: 1427", "C: 1110"]]
howmuch(0, 200)      => [["M: 37", "B: 5", "C: 4"], ["M: 100", "B: 14", "C: 11"], ["M: 163", "B: 23", "C: 18"]]
```

Explanation of the results for `howmuch(1, 100)`:

* In the first answer his possible fortune is **37**:
 * so he can buy 7 boats each worth 5: `37 - 7 * 5 = 2`
 * or he can buy 9 cars worth 4 each: `37 - 9 * 4 = 1`
* The second possible answer is **100**:
 * he can buy 7 boats each worth 14: `100 - 7 * 14 = 2`
 * or he can buy 9 cars worth 11: `100 - 9 * 11 = 1`

user: Given an array containing only integers, add all the elements and return the binary equivalent of that sum.

If the array contains any non-integer element (e.g. an object, a float, a string and so on), return false.

**Note:** The sum of an empty array is zero.

```python
arr2bin([1,2]) == '11'
arr2bin([1,2,'a']) == False
```

Answer: {"fn_name": "arr2bin", "inputs": [[[1, 2]], [[1, 2, 3, 4, 5]], [[1, 10, 100, 1000]], [[1, 2, -1, -2]], [[1, 2, -1, -2, 1]], [[]]], "outputs": [["11"], ["1111"], ["10001010111"], ["0"], ["1"], ["0"]]}
user: Given the current exchange rate between the USD and the EUR is 1.1363636 write a function that will accept the Curency type to be returned and a list of the amounts that need to be converted.

Don't forget this is a currency so the result will need to be rounded to the second decimal. 

'USD' Return format should be `'$100,000.00'`

'EUR' Return format for this kata should be `'100,000.00€'`

`to_currency` is a string with values `'USD','EUR'` , `values_list` is a list of floats

`solution(to_currency,values)`

```
solution('USD',[1394.0, 250.85, 721.3, 911.25, 1170.67])

user: A zero-indexed array ```arr``` consisting of n integers is given. The dominator of array ```arr``` is the value that occurs in more than half of the elements of ```arr```.
For example, consider array ```arr``` such that ```arr = [3,4,3,2,3,1,3,3]``` The dominator of ```arr``` is 3 because it occurs in 5 out of 8 elements of ```arr``` and 5 is more than a half of 8.
Write a function ```dominator(arr)``` that, given a zero-indexed array ```arr``` consisting of n integers, returns the dominator of ```arr```. The function should return −1 if array does not have a dominator. All values in ```arr``` will be >=0.
