user: #### Task:

Your job here is to write a function (`keepOrder` in JS/CoffeeScript, `keep_order` in Ruby/Crystal/Python, `keeporder` in Julia), which takes a sorted array `ary` and a value `val`, and returns the lowest index where you could insert `val` to maintain the sorted-ness of the array. The input array will always be sorted in ascending order. It may contain duplicates.

_Do not modify the input._

#### Some examples:

```python
keep_order([1, 2, 3, 4, 7], 5) #=> 4
                      ^(index 4)
keep_order([1, 2, 3, 4, 7], 0) #=> 0
          ^(index 0)
keep_order([1, 1, 2, 2, 2], 2) #=> 2
                ^(index 2)
```

In this kata you will have to write a function that takes `litres` and `price_per_litre` as arguments. Purchases of 2 or more litres get a discount of 5 cents per litre, purchases of 4 or more litres get a discount of 10 cents per litre, and so on every two litres, up to a maximum discount of 25 cents per litre. But total discount per litre cannot be more than 25 cents. Return the toal cost rounded to 2 decimal places. Also you can guess that there will not be negative or non-numeric inputs.

user: ## The Riddle

The King of a small country invites 1000 senators to his annual party. As a tradition, each senator brings the King a bottle of wine. Soon after, the Queen discovers that one of the senators is trying to assassinate the King by giving him a bottle of poisoned wine. Unfortunately, they do not know which senator, nor which bottle of wine is poisoned, and the poison is completely indiscernible.

However, the King has 10 lab rats. He decides to use them as taste testers to determine which bottle of wine contains the poison. The poison when taken has no effect on the rats, until exactly 24 hours later when the infected rats suddenly die. The King needs to determine which bottle of wine is poisoned by tomorrow, so that the festivities can continue as planned.

Hence he only has time for one round of testing, he decides that each rat tastes multiple bottles, according to a certain scheme.


## Your Task

You receive an array of integers (`0 to 9`), each of them is the number of a rat which died after tasting the wine bottles. Return the number of the bottle (`1..1000`) which is poisoned.


**Good Luck!**


*Hint: think of rats as a certain representation of the number of the bottle...*

user: We have the numbers with different colours with the sequence: ['red', 'yellow', 'blue'].

That sequence colours the numbers in the following way:

 1   2   3    4    5   6  7   8   9   10   11  12   13 .....

We have got the following recursive function:

  ```
f(1) = 1
f(n) = f(n - 1) + n
```

Some terms of this sequence with their corresponding colour are:

```
term   value   colour
1        1     "red"
2        3     "blue"
3        6     "blue"
4       10     "red"
5       15     "blue"
6       21     "blue"
7       28     "red"
```

The three terms of the same colour "blue", higher than 3, are: `[6, 15, 21]`

We need a function `same_col_seq(), that may receive three arguments:

- `val`, an integer number
- `k`, an integer number
- `colour`, the name of one of the three colours(red, yellow or blue), as a string.

The function will output a sorted array with the smallest `k` terms, having the same marked colour, but higher than `val`.

Let's see some examples:

```python
same_col_seq(3, 3, 'blue') == [6, 15, 21]
same_col_seq(100, 4, 'red') == [136, 190, 253, 325]
```

The function may output an empty list if it does not find terms of the sequence with the wanted colour in the range [val, 2* k * val]

```python
same_col_seq(250, 6, 'yellow') == []
```

That means that the function did not find any "yellow" term in the range `[250, 3000]`
 
Tests will be with the following features:

* Nmber of tests: `100`
* `100 < val < 1000000`
* `3 < k < 20`

user: Given a standard english sentence passed in as a string, write a method that will return a sentence made up of the same words, but sorted by their first letter. However, the method of sorting has a twist to it:
* All words that begin with a lower case letter should be at the beginning of the sorted sentence, and sorted in ascending order.
* All words that begin with an upper case letter should come after that, and should be sorted in descending order.

If a word appears multiple times in the sentence, it should be returned multiple times in the sorted sentence. Any punctuation must be discarded.

## Example

For example, given the input string `"Land of the Old Thirteen! Massachusetts land! land of Vermont and Connecticut!"`, your method should return `"and land land of of the Vermont Thirteen Old Massachusetts Land Connecticut"`. Lower case letters are sorted `a -> l -> l -> o -> o -> t` and upper case letters are sorted `V -> T -> O -> M -> L -> C`.

user: You are given array of integers, your task will be to count all pairs in that array and return their count.

**Notes:**
   
* Array can be empty or contain only one value; in this case return `0` 
* If there are more pairs of a certain number, count each pair only once. E.g.: for `[0, 0, 0, 0]` the return value is `2` (= 2 pairs of `0`s)
* Random tests: maximum array length is 1000, range of values in array is between 0 and 1000


## Examples

```
[1, 2, 5, 6, 5, 2]  -->  2
```
...because there are 2 pairs: `2` and `5`

user: ## Task
 In your favorite game, you must shoot a target with a water-gun to gain points. Each target can be worth a different amount of points. 
 
 You are guaranteed to hit every target that you try to hit. You cannot hit consecutive targets though because targets are only visible for one second (one at a time) and it takes you a full second to reload your water-gun after shooting (you start the game already loaded).

 Given an array `vals` with the order of each target's point value, determine the maximum number of points that you can win.

## Example
 For `vals = [1, 2, 3, 4]`, the result should be `6`.
 
 your optimal strategy would be to let the first one pass and shoot the second one with value 2 and the 4th one with value 4 thus:

 `vals[1](2) + vals[3](4) = 6`
 
 For `vals = [5, 5, 5, 5, 5]`, the result should be `15`.
 
 your optimal strategy would be to shoot the 1st, 3rd and 5th value:
 
 `5 + 5 + 5 = 15`
 
 You haven't shoot the 2nd, 4th value because you are reloading your water-gun after shooting other values.
 
 Note that the value can be zero or negative, don't shoot them ;-)
 
 For `vals = [0, 0, -1, -1]`, the result should be `0`.
 
 For `vals = [5, -2, -9, -4]`, the result should be `5`.
 
 Shoot the first one is enough.
 
## Input/Output


 - `[input]` integer array `vals`

user: Ever since you started work at the grocer, you have been faithfully logging down each item and its category that passes through. One day, your boss walks in and asks, "Why are we just randomly placing the items everywhere? It's too difficult to find anything in this place!" Now's your chance to improve the system, impress your boss, and get that raise!

The input is a comma-separated list with category as the prefix in the form `"fruit_banana"`. Your task is to group each item into the 4 categories `Fruit, Meat, Other, Vegetable` and output a string with a category on each line followed by a sorted comma-separated list of items.

For example, given:

user: Uh oh, Someone at the office has dropped all these sequences on the floor and forgotten to label them with their correct bases. 

We have to fix this before the boss gets back or we're all going to be fired!

This is what your years of coding have been leading up to, now is your time to shine!

## Task

You will have to create a function which takes in a sequence of numbers in **random order** and you will have to return the correct base of those numbers.

The base is the number of unique digits. For example, a base 10 number can have 10 unique digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and a base 2 number (Binary) can have 2 unique digits: 0 and 1.

### Constraints

The sequence will always be 10 numbers long and we know that the base is going to be between 2 and 10 inclusive so no need to worry about any letters. When sorted, the sequence is made up of consecutive numbers.

### Examples

```
[ "1", "2", "3", "4", "5", "6", "7", "8", "9", "10" ]     -->  10
[ "1", "2", "3", "4", "5", "6", "10", "11", "12", "13" ]  -->   7

user: For a given two numbers your mission is to derive a function that evaluates whether two given numbers are **abundant**, **deficient** or **perfect** and whether together they are **amicable**.



### Abundant Numbers
An abundant number or excessive number is a number for which the sum of its proper divisors is greater than the number itself.

The integer 12 is the first abundant number. Its proper divisors are 1, 2, 3, 4 and 6 for a total of 16 (> 12).

### Deficient Numbers
A deficient number is a number for which the sum of its proper divisors is less than the number itself.

The first few deficient numbers are: 1, 2, 3, 4, 5, 7, 8, 9.

### Perfect Numbers
A perfect number is a positive integer that is equal to the sum of its proper positive divisors, that is, the sum of its positive divisors excluding the number itself. 

The first perfect number is 6, because 1, 2, and 3 are its proper positive divisors, and 1 + 2 + 3 = 6.

### Amicable Numbers
Amicable numbers are two different numbers so related that the sum of the proper divisors of each is equal to the other number. (A proper divisor of a number is a positive factor of that number other than the number itself. For example, the proper divisors of 6 are 1, 2, and 3.)

For example, the smallest pair of amicable numbers is (220, 284); for the proper divisors of 220 are 1, 2, 4, 5, 10, 11, 20, 22, 44, 55 and 110, of which the sum is 284; and the proper divisors of 284 are 1, 2, 4, 71 and 142, of which the sum is 220.

### The Function

For a given two numbers, derive function `deficientlyAbundantAmicableNumbers(num1, num2)` which returns a string with first and second word either abundant or deficient depending on whether `num1` or `num2` are abundant, deficient or perfect. The string should finish with either amicable or not amicable depending on the relationship between `num1` and `num2`.

e.g. `deficientlyAbundantAmicableNumbers(220, 284)` returns `"abundant deficient amicable"` as 220 is an abundant number, 284 is a deficient number and amicable because 220 and 284 are an amicable number pair.

user: Similar to the [previous kata](https://www.codewars.com/kata/string-subpattern-recognition-ii/), but this time you need to operate with shuffled strings to identify if they are composed repeating a subpattern

Since there is no deterministic way to tell which pattern was really the original one among all the possible permutations of a fitting subpattern, return a subpattern with sorted characters, otherwise return the base string with sorted characters (you might consider this case as an edge case, with the subpattern being repeated only once and thus equalling the original input string).

For example:

```python
has_subpattern("a") == "a"; #no repeated pattern, just one character
has_subpattern("aaaa") == "a" #just one character repeated
has_subpattern("abcd") == "abcd" #base pattern equals the string itself, no repetitions
has_subpattern("babababababababa") == "ab" #remember to return the base string sorted"
has_subpattern("bbabbaaabbaaaabb") == "ab" #same as above, just shuffled
```
