# Diffie-Hellman
Diffie-Hellman key exchange.
Alice and Bob use Diffie-Hellman key exchange to share secrets. They
start with prime numbers, pick private keys, generate and share public
keys, and then generate a shared secret key.
## Step 0
The test program supplies prime numbers p and g.
## Step 1
Alice picks a private key, a, greater than 1 and less than p. Bob does
the same to pick a private key b.
## Step 2
Alice calculates a public key A.
A = g**a mod p
Using the same p and g, Bob similarly calculates a public key B from his
private key b.
## Step 3
Alice and Bob exchange public keys. Alice calculates secret key s.
s = B**a mod p
Bob calculates
s = A**b mod p
The calculations produce the same result! Alice and Bob now share
secret s.
## Setup
Go through the setup instructions for Kotlin to install the necessary
dependencies:
[https://exercism.io/tracks/kotlin/installation](https://exercism.io/tracks/kotlin/installation)
## Making the test suite pass
Execute the tests with:
```bash
$ gradlew test
```
> Use `gradlew.bat` if you're on Windows
In the test suites all tests but the first have been skipped.
Once you get a test passing, you can enable the next one by removing the
`@Ignore` annotation.

# Dominoes
Make a chain of dominoes.
Compute a way to order a given set of dominoes in such a way that they form a
correct domino chain (the dots on one half of a stone match the dots on the
neighbouring half of an adjacent stone) and that dots on the halves of the
stones which don't have a neighbour (the first and last stone) match each other.
For example given the stones `[2|1]`, `[2|3]` and `[1|3]` you should compute something
like `[1|2] [2|3] [3|1]` or `[3|2] [2|1] [1|3]` or `[1|3] [3|2] [2|1]` etc, where the first and last numbers are the same.
For stones `[1|2]`, `[4|1]` and `[2|3]` the resulting chain is not valid: `[4|1] [1|2] [2|3]`'s first and last numbers are not the same. 4 != 3
Some test cases may use duplicate stones in a chain solution, assume that multiple Domino sets are being used.
## Setup
Go through the setup instructions for Kotlin to install the necessary
dependencies:
[https://exercism.io/tracks/kotlin/installation](https://exercism.io/tracks/kotlin/installation)
## Making the test suite pass

# Kindergarten Garden
Given a diagram, determine which plants each child in the kindergarten class is
responsible for.
The kindergarten class is learning about growing plants. The teacher
thought it would be a good idea to give them actual seeds, plant them in
actual dirt, and grow actual plants.
They've chosen to grow grass, clover, radishes, and violets.
To this end, the children have put little cups along the window sills, and
planted one type of plant in each cup, choosing randomly from the available
types of seeds.
```text
[window][window][window]
........................ # each dot represents a cup
........................
```
There are 12 children in the class:
- Alice, Bob, Charlie, David,
- Eve, Fred, Ginny, Harriet,
- Ileana, Joseph, Kincaid, and Larry.
Each child gets 4 cups, two on each row. Their teacher assigns cups to
the children alphabetically by their names.
The following diagram represents Alice's plants:
```text
[window][window][window]
VR......................
RG......................
```
In the first row, nearest the windows, she has a violet and a radish. In the
second row she has a radish and some grass.
Your program will be given the plants from left-to-right starting with
the row nearest the windows. From this, it should be able to determine
which plants belong to each student.
For example, if it's told that the garden looks like so:
```text
[window][window][window]
VRCGVVRVCGGCCGVRGCVCGCGV
VRCCCGCRRGVCGCRVVCVGCGCV
```
Then if asked for Alice's plants, it should provide:
- Violets, radishes, violets, radishes
While asking for Bob's plants would yield:
- Clover, grass, clover, clover
# Running the tests
You can run all the tests for an exercise by entering
```sh
$ ./gradlew test
```
in your terminal.
## Source
Random musings during airplane trip. [http://jumpstartlab.com](http://jumpstartlab.com)
## Submitting Incomplete Solutions
It's possible to submit an incomplete solution so you can see how others have completed the exercise.

# Score a single throw of dice in *Yacht*
The dice game [Yacht](https://en.wikipedia.org/wiki/Yacht_(dice_game)) is from
the same family as Poker Dice, Generala and particularly Yahtzee, of which it
is a precursor. In the game, five dice are rolled and the result can be entered
in any of twelve categories. The score of a throw of the dice depends on
category chosen.
## Scores in Yacht
| Category | Score | Description | Example |
| -------- | ----- | ----------- | ------- |
| Ones | 1 × number of ones | Any combination | 1 1 1 4 5 scores 3 |
| Twos | 2 × number of twos | Any combination | 2 2 3 4 5 scores 4 |
| Threes | 3 × number of threes | Any combination | 3 3 3 3 3 scores 15 |
| Fours | 4 × number of fours | Any combination | 1 2 3 3 5 scores 0 |
| Fives | 5 × number of fives| Any combination | 5 1 5 2 5 scores 15 |
| Sixes | 6 × number of sixes | Any combination | 2 3 4 5 6 scores 6 |
| Full House | Total of the dice | Three of one number and two of another | 3 3 3 5 5 scores 19 |
| Four of a Kind | Total of the four dice | At least four dice showing the same face | 4 4 4 4 6 scores 16 |
| Little Straight | 30 points | 1-2-3-4-5 | 1 2 3 4 5 scores 30 |
| Big Straight | 30 points | 2-3-4-5-6 | 2 3 4 5 6 scores 30 |
| Choice | Sum of the dice | Any combination | 2 3 3 4 6 scores 18 |
| Yacht | 50 points | All five dice showing the same face | 4 4 4 4 4 scores 50 |
If the dice do not satisfy the requirements of a category, the score is zero.
If, for example, *Four Of A Kind* is entered in the *Yacht* category, zero
points are scored. A *Yacht* scores zero if entered in the *Full House* category.
## Task
Given a list of values for five dice and a category, your solution should return
the score of the dice for that category. If the dice do not satisfy the requirements
of the category your solution should return 0. You can assume that five values
will always be presented, and the value of each will be between one and six
inclusively. You should not assume that the dice are ordered.
## Setup
Go through the setup instructions for Kotlin to install the necessary
dependencies:
[https://exercism.io/tracks/kotlin/installation](https://exercism.io/tracks/kotlin/installation)
## Making the test suite pass
Execute the tests with:
```bash
$ ./gradlew test
```
> Use `gradlew.bat` if you're on Windows
In the test suites all tests but the first have been skipped.
Once you get a test passing, you can enable the next one by removing the
`@Ignore` annotation.

## Submitting Incomplete Solutions
It's possible to submit an incomplete solution so you can see how others have
completed the exercise.
