user: You have managed to intercept an important message and you are trying to read it.

You realise that the message has been encoded and can be decoded by switching each letter with a corresponding letter.

You also notice that each letter is paired with the letter that it coincides with when the alphabet is reversed.

For example: "a" is encoded with "z", "b" with "y", "c" with "x", etc

You read the first sentence:
```
"r slkv mlylwb wvxlwvh gsrh nvhhztv"
```

After a few minutes you manage to decode it:
```
"i hope nobody decodes this message"
```
Create a function that will instantly decode any of these messages

You can assume no punctuation or capitals, only lower case letters, but remember spaces!

user: Jump is a simple one-player game:

You are initially at the first cell of an array of cells containing non-negative integers;

At each step you can jump ahead in the array as far as the integer at the current cell, or any smaller number of cells.
You win if there is a path that allows you to jump from one cell to another, eventually jumping past the end of the array, otherwise you lose.

For instance, if the array contains the integers 

`[2, 0, 3, 5, 0, 0, 3, 0, 0, 3, 1, 0]`,

you can win by jumping from **2**, to **3**, to **5**, to **3**, to **3**, then past the end of the array.

You can also directly jump from from the initial cell(first cell) past the end of the array if they are integers to the right of that cell.

E.g 

`[6, 1, 1]` is winnable

`[6]` is **not** winnable

Note: You can **not** jump from the last cell!

`[1, 1, 3]` is **not** winnable

## -----

Your task is to complete the function `canJump()`  that determines if a given game is winnable.

### More Examples

``` javascript
canJump([5]) //=> false
canJump([2, 5]) //=> true
canJump([3, 0, 2, 3]) //=> true (3 to 2 then past end of array)
canJump([4, 1, 2, 0, 1]) //=> false
canJump([5, 0, 0, 0]) //=> true
canJump([1, 1]) //=> false
```

user: Your task is to calculate logical value of boolean array. Test arrays are one-dimensional and their size is in the range 1-50.

Links referring to logical operations: [AND](https://en.wikipedia.org/wiki/Logical_conjunction), [OR](https://en.wikipedia.org/wiki/Logical_disjunction) and [XOR](https://en.wikipedia.org/wiki/Exclusive_or).

You should begin at the first value, and repeatedly apply the logical operation across the remaining elements in the array sequentially.

First Example:

Input: true, true, false, operator: AND

Steps: true AND true -> true, true AND false -> false

Output: false

Second Example:

Input: true, true, false, operator: OR

Steps: true OR true -> true, true OR false -> true

Output: true

Third Example:

Input: true, true, false, operator: XOR

Steps: true XOR true -> false, false XOR false -> false

Output: false

Input:

boolean array, string with operator' s name: 'AND', 'OR', 'XOR'.

user: You need to write a function, that returns the first non-repeated character in the given string.

For example for string `"test"` function should return `'e'`.  
For string `"teeter"` function should return `'r'`.  
  
If a string contains all unique characters, then return just the first character of the string.  
Example: for input `"trend"` function should return `'t'`  
  
You can assume, that the input string has always non-zero length.

If there is no repeating character, return `null` in JS or Java, and `None` in Python.

Answer: {"fn_name": "first_non_repeated", "inputs": [["test"], ["teeter"], ["1122321235121222"], ["rend"]], "outputs": [["e"], ["r"], ["5"], ["r"]]}
user: Similarly to the [previous kata](https://www.codewars.com/kata/string-subpattern-recognition-i/), you will need to return a boolean value if the base string can be expressed as the repetition of one subpattern.

This time there are two small changes:

* if a subpattern has been used, it will be repeated at least twice, meaning the subpattern has to be shorter than the original string;
* the strings you will be given might or might not be created repeating a given subpattern, then shuffling the result.

For example:

```python
has_subpattern("a") == False #no repeated shorter sub-pattern, just one character
has_subpattern("aaaa") == True #just one character repeated
has_subpattern("abcd") == False #no repetitions
has_subpattern("babababababababa") == True #repeated "ba"
has_subpattern("bbabbaaabbaaaabb") == True #same as above, just shuffled
```
Strings will never be empty and can be composed of any character (just consider upper- and lowercase letters as different entities) and can be pretty long (keep an eye on performances!).

user: For this problem you must create a program that says who ate the last cookie. If the input is a string then "Zach" ate the cookie. If the input is a float or an int then "Monica" ate the cookie. If the input is anything else "the dog" ate the cookie. The way to return the statement is:
"Who ate the last cookie? It was (name)!"

Ex: Input = "hi" --> Output = "Who ate the last cookie? It was Zach!
(The reason you return Zach is because the input is a string)

Note: Make sure you return the correct message with correct spaces and punctuation.

user: Lot of junior developer can be stuck when they need to change the access permission to a file or a directory in an Unix-like operating systems.

To do that they can use the `chmod` command and with some magic trick they can change the permissionof a file or a directory. For more information about the `chmod` command you can take a look at the [wikipedia page](https://en.wikipedia.org/wiki/Chmod).

`chmod` provides two types of syntax that can be used for changing permissions. An absolute form using octal to denote which permissions bits are set e.g: 766.
Your goal in this kata is to define the octal you need to use in order to set yout permission correctly.

Here is the list of the permission you can set with the octal representation of this one.

- User
  - read (4)
  - write (2)
  - execute (1)
- Group
  - read (4)
  - write (2)
  - execute (1)
- Other
  - read (4)
  - write (2)
  - execute (1)
  
The method take a hash in argument this one can have a maximum of 3 keys (`owner`,`group`,`other`). Each key will have a 3 chars string to represent the permission, for example the string `rw-` say that the user want the permission `read`, `write` without the `execute`.
If a key is missing set the permission to `---`

**Note**: `chmod` allow you to set some special flags too (`setuid`, `setgid`, `sticky bit`) but to keep some simplicity for this kata we will ignore this one.

user: Your task is very simple. Given an input string s, case\_sensitive(s), check whether all letters are lowercase or not. Return True/False and a list of all the entries that are not lowercase in order of their appearance in s.

For example, case\_sensitive('codewars') returns [True, []], but case\_sensitive('codeWaRs') returns [False, ['W', 'R']].

user: You throw a ball vertically upwards with an initial speed `v (in km per hour)`. The height `h` of the ball at each time `t`
is given by `h = v*t - 0.5*g*t*t` where `g` is Earth's gravity `(g ~ 9.81 m/s**2)`. A device is recording at every **tenth
of second** the height of the ball.
For example with `v = 15 km/h` the device gets something of the following form:
`(0, 0.0), (1, 0.367...), (2, 0.637...), (3, 0.808...), (4, 0.881..) ...`
where the first number is the time in tenth of second and the second number the height in meter.
# Task
Write a function `max_ball` with parameter `v (in km per hour)` that returns the `time in tenth of second`
of the maximum height recorded by the device.
# Examples:
`max_ball(15) should return 4`

`max_ball(25) should return 7`
# Notes
- Remember to convert the velocity from km/h to m/s or from m/s in km/h when necessary.
- The maximum height recorded by the device is not necessarily the maximum height reached by the ball.

user: 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).

user: [Haikus](https://en.wikipedia.org/wiki/Haiku_in_English) are short poems in a three-line format, with 17 syllables arranged in a 5–7–5 pattern. Your task is to check if the supplied text is a haiku or not.


### About syllables

[Syllables](https://en.wikipedia.org/wiki/Syllable) are the phonological building blocks of words. *In this kata*, a syllable is a part of a word including a vowel ("a-e-i-o-u-y") or a group of vowels (e.g. "ou", "ee", "ay"). A few examples: "tea", "can", "to·day", "week·end", "el·e·phant".

**However**, silent "E"s **do not** create syllables. *In this kata*, an "E" is considered silent if it's alone at the end of the word, preceded by one (or more) consonant(s) and there is at least one other syllable in the word. Examples: "age", "ar·range", "con·crete"; but not in "she", "blue", "de·gree".

Some more examples:
* one syllable words: "cat", "cool", "sprout", "like", "eye", "squeeze"
* two syllables words: "ac·count", "hon·est", "beau·ty", "a·live", "be·cause", "re·store"


## Examples
```
An old silent pond...
A frog jumps into the pond,
splash! Silence again.
```

...should return `True`, as this is a valid 5–7–5 haiku:
```
An old si·lent pond...            # 5 syllables
A frog jumps in·to the pond,      # 7
splash! Si·lence a·gain.          # 5
```

Another example:

```
Autumn moonlight -
a worm digs silently
into the chestnut.
```

...should return `False`, because the number of syllables per line is not correct:
```
Au·tumn moon·light -          # 4 syllables
a worm digs si·lent·ly        # 6
in·to the chest·nut.          # 5
```

user: # Task
 Consider a string of lowercase Latin letters and space characters (" "). 
 
 First, rearrange the letters in each word `alphabetically`. 
 
 And then rearrange the words in ascending order of the sum of their characters' `ASCII` values. 
 
 If two or more words have the same `ASCII` value, rearrange them by their length in ascending order; If their length still equals to each other, rearrange them `alphabetically`.
 
 Finally, return the result.

# Example

 For `s = "batman is bruce wayne"`, the result should be `"is bceru aenwy aamntb"`.
``` 
After rearranging the letters the string turns into
"aamntb is bceru aenwy".
The ASCII values of each word are: [627, 220, 529, 548].
After sorting the words the following string is obtained:
"is bceru aenwy aamntb" (with ASCII values of [220, 529, 548, 627]).```

user: I have the `par` value for each hole on a golf course and my stroke `score` on each hole. I have them stored as strings, because I wrote them down on a sheet of paper.  Right now, I'm using those strings to calculate my golf score by hand: take the difference between my actual `score` and the `par` of the hole, and add up the results for all 18 holes.

For example:
* If I took 7 shots on a hole where the par was 5, my score would be: 7 - 5 = 2
* If I got a hole-in-one where the par was 4, my score would be: 1 - 4 = -3.

Doing all this math by hand is really hard! Can you help make my life easier?


## Task Overview

Complete the function which accepts two strings and calculates the golf score of a game. Both strings will be of length 18, and each character in the string will be a number between 1 and 9 inclusive.

Answer: {"fn_name": "golf_score_calculator", "inputs": [["443454444344544443", "353445334534445344"], ["123456123456123456", "123456123456123456"]], "outputs": [[-1], [0]]}
user: The written representation of a number (with 4 or more digits) can be split into three parts in various different ways. For example, the written number 1234 can be split as [1 | 2 | 34] or [1 | 23 | 4] or [12 | 3 | 4].

Given a written number, find the highest possible product from splitting it into three parts and multiplying those parts together. For example:

- product of [1 | 2 | 34] = 1 \* 2 \* 34 = 68
- product of [1 | 23 | 4] = 1 \* 23 \* 4 = 92
- product of [12 | 3 | 4] = 12 \* 3 \* 4 = 144

So maximumProductOfParts(1234) = 144

For a longer string there will be many possible different ways to split it into parts. For example, 8675309 could be split as: 

- [8 | 6 | 75309] 
- [867 | 530 | 9] 
- [8 | 67 | 5309]
- [86 | 75 | 309]

or any other option that splits the string into three parts each containing at least one digit.

Answer: {"fn_name": "maximum_product_of_parts", "inputs": [[1234], [4321], [4224]], "outputs": [[144], [252], [352]]}
