user: Do you have in mind the good old TicTacToe?

Assuming that you get all the data in one array, you put a space around each value, `|` as a columns separator and multiple `-` as rows separator, with something like `["O", "X", " ", " ", "X", " ", "X", "O", " "]` you should be returning this structure (inclusive of new lines):

```
 O | X |   
-----------
   | X |   
-----------
 X | O |   
```

Now, to spice up things a bit, we are going to expand our board well beyond a trivial `3` x `3` square and we will accept rectangles of big sizes, still all as a long linear array.

For example, for `"O", "X", " ", " ", "X", " ", "X", "O", " ", "O"]` (same as above, just one extra `"O"`) and knowing that the length of each row is `5`, you will be returning

```
 O | X |   |   | X 
-------------------
   | X | O |   | O 
```

And worry not about missing elements, as the array/list/vector length is always going to be a multiple of the width.

user: # Task
 You are the manager of the famous rescue team: The Knights. Your task is to assign your knights to a rescue missions on an infinite 2D-plane.

 Your knights can move only by `n-knight` jumps. 
 
 For example, if a knight has n = 2, they can only move exactly as a knight on a chess board. 
 
 If n = 3, they can move from (0, 0) to one of the following 8 points:

 `(3, 1) (3, -1), ( -3, 1), (-3, -1), (1, 3), (1, -3), (-1, 3) or (-1, -3).`

 You are given an array containing the `n`s of all of your knights `n-knight` jumps, and the coordinates (`x`, `y`) of a civilian who need your squad's help.

 Your head quarter is located at (0, 0). Your must determine if `at least one` of your knight can reach that point `(x, y)`.

# Input/Output


 - `[input]` integer array `N`

  The ways your knights move. 
  
  `1 <= N.length <=20`


 - `[input]` integer `x`

  The x-coordinate of the civilian


 - `[input]` integer `y`

  The y-coordinate of the civilian


 - `[output]` a boolean value

 `true` if one of your knights can reach point (x, y), `false` otherwise.

user: You are given a sequence of a journey in London, UK. The sequence will contain bus **numbers** and TFL tube names as **strings** e.g.

```python
['Northern', 'Central', 243, 1, 'Victoria']
```
Journeys will always only contain a combination of tube names and bus numbers. Each tube journey costs `£2.40` and each bus journey costs `£1.50`. If there are `2` or more adjacent bus journeys, the bus fare is capped for sets of two adjacent buses and calculated as one bus fare for each set.

Your task is to calculate the total cost of the journey and return the cost `rounded to 2 decimal places` in the format (where x is a number): `£x.xx`

user: **Story**  
On some island lives a chameleon population. Chameleons here can be of only one of three colors - red, green and blue. Whenever two chameleons of different colors meet, they can change their colors to a third one (i.e. when red and blue chameleons meet, they can both become green). There is no other way for chameleons to change their color (in particular, when red and blue chameleons meet, they can't become both red, only third color can be assumed).  
Chameleons want to become of one certain color. They may plan they meetings to reach that goal. Chameleons want to know, how fast their goal can be achieved (if it can be achieved at all).

**Formal problem**  
*Input:*  
Color is coded as integer, 0 - red, 1 - green, 2 - blue.
Chameleon starting population is given as an array of three integers, with index corresponding to color (i.e. [2, 5, 3] means 2 red, 5 green and 3 blue chameleons). All numbers are non-negative, their sum is between `1` and `int.MaxValue` (maximal possible value for `int` type, in other languages). Desired color is given as an integer from 0 to 2.  
*Output:*  
`Kata.Chameleon` should return *minimal* number of meetings required to change all chameleons to a given color, or -1 if it is impossible (for example, if all chameleons are initially of one other color).  
  
**Notes and hints**  
-- Some tests use rather big input values. Be effective.  
-- There is a strict proof that answer is either -1 or no greater than total number of chameleons (thus, return type `int` is justified). Don't worry about overflow.

user: Your friend has invited you to a party, and tells you to meet them in the line to get in. The one problem is it's a masked party. Everyone in line is wearing a colored mask, including your friend. Find which people in line could be your friend.

Your friend has told you that he will be wearing a `RED` mask, and has **TWO** other friends with him, both wearing `BLUE` masks.

Input to the function will be an array of strings, each representing a colored mask. For example:
```python
line = ['blue','blue','red','red','blue','green']
```

The output of the function should be the number of people who could possibly be your friend.
```python
friend_find(['blue','blue','red','red','blue','green','chipmunk'])  # return 1

user: Pig Latin is an English language game where the goal is to hide the meaning of a word from people not aware of the rules.

So, the goal of this kata is to wite a function that encodes a single word string to pig latin.

The rules themselves are rather easy:

1) The word starts with a vowel(a,e,i,o,u) -> return the original string plus "way".

2) The word starts with a consonant -> move consonants from the beginning of the word to the end of the word until the first vowel, then return it plus "ay".

3) The result must be lowercase, regardless of the case of the input. If the input string has any non-alpha characters, the function must return None, null, Nothing (depending on the language).

4) The function must also handle simple random strings and not just English words.

5) The input string has no vowels -> return the original string plus "ay".

For example, the word "spaghetti" becomes "aghettispay" because the first two letters ("sp") are consonants, so they are moved to the end of the string and "ay" is appended.

user: Mrs Jefferson is a great teacher. One of her strategies that helped her to reach astonishing results in the learning process is to have some fun with her students. At school, she wants to make an arrangement of her class to play a certain game with her pupils. For that, she needs to create the arrangement with **the minimum amount of groups that have consecutive sizes**.

Let's see. She has      ```14``` students. After trying a bit she could do the needed arrangement:
        ```[5, 4, 3, 2]```
- one group of  ```5``` students
- another group of      ```4``` students
- then, another one of  ```3``` 
- and finally, the smallest group of    ```2``` students.

As the game was a success, she was asked to help to the other classes to teach and show the game. That's why she desperately needs some help to make this required arrangements that make her spend a lot of time. 

To make things worse, she found out that there are some classes with some special number of students that is impossible to get that arrangement.

Please, help this teacher!

Your code will receive the number of students of the class. It should output the arrangement as an array with the consecutive sizes of the groups in decreasing order.

For the special case that no arrangement of the required feature is possible the code should output     ```[-1] ```

The value of n is unknown and may be pretty high because some classes joined to to have fun with the game.

You may see more example tests in the Example Tests Cases Box.

user: *This kata is based on [Project Euler Problem #349](https://projecteuler.net/problem=349). You may want to start with solving [this kata](https://www.codewars.com/kata/langtons-ant) first.*

---

[Langton's ant](https://en.wikipedia.org/wiki/Langton%27s_ant) moves on a regular grid of squares that are coloured either black or white.
The ant is always oriented in one of the cardinal directions (left, right, up or down) and moves  according to the following rules:
- if it is on a black square, it flips the colour of the square to white, rotates 90 degrees counterclockwise and moves forward one square.
- if it is on a white square, it flips the colour of the square to black, rotates 90 degrees clockwise and moves forward one square.

Starting with a grid that is **entirely white**, how many squares are black after `n` moves of the ant?

**Note:** `n` will go as high as 10^(20)

user: **Introduction**
 Little Petya very much likes sequences. However, recently he received a sequence as a gift from his mother.
 Petya didn't like it at all! He decided to make a single replacement. After this replacement, Petya would like to the sequence in increasing order.
 He asks himself: What is the lowest possible value I could have got after making the replacement and sorting the sequence?

**About the replacement**
 Choose exactly one element from the sequence and replace it with another integer > 0. You are **not allowed** to replace a number with itself, or to change no number at all.

**Task**
 Find the lowest possible sequence after performing a valid replacement, and sorting the sequence.

**Input:**
 Input contains sequence with `N` integers. All elements of the sequence > 0. The sequence will never be empty.

**Output:**
 Return sequence with `N` integers — which includes the lowest possible values of each sequence element, after the single replacement and sorting has been performed.

**Examples**:
```
([1,2,3,4,5])  =>  [1,1,2,3,4]
([4,2,1,3,5])  =>  [1,1,2,3,4]
([2,3,4,5,6])  =>  [1,2,3,4,5]
([2,2,2])      =>  [1,2,2]

user: What is an anagram? Well, two words are anagrams of each other if they both contain the same letters. For example:

```
'abba' & 'baab' == true

'abba' & 'bbaa' == true

'abba' & 'abbba' == false

'abba' & 'abca' == false
```

Write a function that will find all the anagrams of a word from a list. You will be given two inputs a word and an array with words. You should return an array of all the anagrams or an empty array if there are none. For example:

anagrams('abba', ['aabb', 'abcd', 'bbaa', 'dada']) => ['aabb', 'bbaa']

anagrams('racer', ['crazer', 'carer', 'racar', 'caers', 'racer']) => ['carer', 'racer']

anagrams('laser', ['lazing', 'lazy',  'lacer']) => []

user: *Shamelessly stolen from Here :)*

Your server has sixteen memory banks; each memory bank can hold any number of blocks. You must write a routine to balance the blocks between the memory banks.

The reallocation routine operates in cycles. In each cycle, it finds the memory bank with the most blocks (ties won by the lowest-numbered memory bank) and redistributes those blocks among the banks. To do this, it removes all of the blocks from the selected bank, then moves to the next (by index) memory bank and inserts one of the blocks. It continues doing this until it runs out of blocks; if it reaches the last memory bank, it wraps around to the first one.

We need to know how many redistributions can be done before a blocks-in-banks configuration is produced that has been seen before.

For example, imagine a scenario with only four memory banks:

* The banks start with 0, 2, 7, and 0 blocks (`[0,2,7,0]`). The third bank has the most blocks (7), so it is chosen for redistribution.
* Starting with the next bank (the fourth bank) and then continuing one block at a time, the 7 blocks are spread out over the memory banks. The fourth, first, and second banks get two blocks each, and the third bank gets one back. The final result looks like this: 2 4 1 2.
* Next, the second bank is chosen because it contains the most blocks (four). Because there are four memory banks, each gets one block. The result is: 3 1 2 3.
* Now, there is a tie between the first and fourth memory banks, both of which have three blocks. The first bank wins the tie, and its three blocks are distributed evenly over the other three banks, leaving it with none: 0 2 3 4.
* The fourth bank is chosen, and its four blocks are distributed such that each of the four banks receives one: 1 3 4 1.
* The third bank is chosen, and the same thing happens: 2 4 1 2.
At this point, we've reached a state we've seen before: 2 4 1 2 was already seen. The infinite loop is detected after the fifth block redistribution cycle, and so the answer in this example is 5.

Return the number of redistribution cycles completed before a configuration is produced that has been seen before.

People seem to be struggling, so here's a visual walkthrough of the above example: http://oi65.tinypic.com/dmshls.jpg

Note: Remember, memory access is very fast. Yours should be too.

**Hint for those who are timing out:** Look at the number of cycles happening even in the sample tests. That's a _lot_ of different configurations, and a lot of different times you're going to be searching for a matching sequence. Think of ways to cut down on the time this searching process takes.

user: ## Story

There are four warriors, they need to go through a dark tunnel. Tunnel is very narrow, every time only can let two warriors through, and there are lot of dangerous traps. Fortunately, they have a lamp that can illuminate the tunnel to avoid being trapped by the trap.

In order to pass this tunnel, they need five steps:

1. Two people go through the tunnel with the lamp
2. And then one people come back with the lamp
3. And then two people go through the tunnel with the lamp
4. And then one people come back with the lamp
5. And then two people go through the tunnel with the lamp
 
Each warrior has his own walking speed, we need to calculate the shortest time they have to cross the tunnel.
 
For example:
 
Four warriors is `a,b,c,d`. Their speed are `[3,4,5,6]`. It means they need 3 minutes, 4 minutes, 5 minutes and 6 minutes to cross the tunnel. The shortest crossing time should be 21 minutes, the method is as follows:
 
```
a and b go through the tunnel  ---> Spend 4 minutes
(Time spent should be calculated by the person who is slow)
a come back                    ---> Spend 3 minutes
a and c go through the tunnel  ---> Spend 5 minutes
a come back                    ---> Spend 3 minutes
a and d go through the tunnel  ---> Spend 6 minutes
```
Do you have any other better way?
 
## Task
Complete function `shortestTime()` that accepts 1 argument: `speed` that are the spent time of four warriors. Returns the shortest time that all warriors go through the tunnel.
 
**Note: The method in example above is not always the best way.**

## Example

Answer: {"fn_name": "shortest_time", "inputs": [[[3, 4, 5, 6]], [[3, 7, 10, 18]], [[5, 5, 6, 7]], [[5, 6, 30, 40]]], "outputs": [[21], [41], [27], [63]]}
user: In this Kata, you will be given two positive integers `a` and `b` and your task will be to apply the following operations:

```
i) If a = 0 or b = 0, return [a,b]. Otherwise, go to step (ii);
ii) If a ≥ 2*b, set a = a - 2*b, and repeat step (i). Otherwise, go to step (iii);
iii) If b ≥ 2*a, set b = b - 2*a, and repeat step (i). Otherwise, return [a,b].
```

`a` and `b` will both be lower than 10E8.

More examples in tests cases. Good luck!

user: Simple, remove the spaces from the string, then return the resultant string.

~~~if:c
For C, you must return a new dynamically allocated string.
