# Armstrong Numbers
Welcome to Armstrong Numbers on Exercism's Dart Track.
If you need help running the tests or submitting your code, check out `HELP.md`.
## Instructions
An [Armstrong number][armstrong-number] is a number that is the sum of its own digits each raised to the power of the number of digits.
For example:
- 9 is an Armstrong number, because `9 = 9^1 = 9`
- 10 is *not* an Armstrong number, because `10 != 1^2 + 0^2 = 1`
- 153 is an Armstrong number, because: `153 = 1^3 + 5^3 + 3^3 = 1 + 125 + 27 = 153`
- 154 is *not* an Armstrong number, because: `154 != 1^3 + 5^3 + 4^3 = 1 + 125 + 64 = 190`
Write some code to determine whether a number is an Armstrong number.

# Difference of Squares
Welcome to Difference of Squares on Exercism's Dart Track.
If you need help running the tests or submitting your code, check out `HELP.md`.
## Instructions
Find the difference between the square of the sum and the sum of the squares of the first N natural numbers.
The square of the sum of the first ten natural numbers is
(1 + 2 + ... + 10)² = 55² = 3025.
The sum of the squares of the first ten natural numbers is
1² + 2² + ... + 10² = 385.
Hence the difference between the square of the sum of the first ten natural numbers and the sum of the squares of the first ten natural numbers is 3025 - 385 = 2640.
You are not expected to discover an efficient solution to this yourself from first principles; research is allowed, indeed, encouraged.
Finding the best algorithm for the problem is a key skill in software engineering.

# Forth
Welcome to Forth on Exercism's Dart Track.
If you need help running the tests or submitting your code, check out `HELP.md`.
## Instructions
Implement an evaluator for a very simple subset of Forth.
[Forth][forth]
is a stack-based programming language.
Implement a very basic evaluator for a small subset of Forth.
Your evaluator has to support the following words:
- `+`, `-`, `*`, `/` (integer arithmetic)
- `DUP`, `DROP`, `SWAP`, `OVER` (stack manipulation)
Your evaluator also has to support defining new words using the customary syntax: `: word-name definition ;`.
To keep things simple the only data type you need to support is signed integers of at least 16 bits size.
You should use the following rules for the syntax: a number is a sequence of one or more (ASCII) digits, a word is a sequence of one or more letters, digits, symbols or punctuation that is not a number.
(Forth probably uses slightly different rules, but this is close enough.)
Words are case-insensitive.

# Hello World
The classical introductory exercise. Just say "Hello, World!".
Welcome to Hello World on Exercism's Dart Track.
If you need help running the tests or submitting your code, check out `HELP.md`.
["Hello, World!"](http://en.wikipedia.org/wiki/%22Hello,_world!%22_program) is
the traditional first program for beginning programming in a new language
or environment.
## Instructions
The classical introductory exercise.
Just say "Hello, World!".
["Hello, World!"][hello-world] is the traditional first program for beginning programming in a new language or environment.
The objectives are simple:

# High Scores
Welcome to High Scores on Exercism's Dart Track.
If you need help running the tests or submitting your code, check out `HELP.md`.
## Instructions
Manage a game player's High Score list.
Your task is to build a high-score component of the classic Frogger game, one of the highest selling and most addictive games of all time, and a classic of the arcade era.
Your task is to write methods that return the highest score from the list, the last added score and the three highest scores.

# Leap
Welcome to Leap on Exercism's Dart Track.
If you need help running the tests or submitting your code, check out `HELP.md`.
## Instructions
Given a year, report if it is a leap year.
The tricky thing here is that a leap year in the Gregorian calendar occurs:
```text
on every year that is evenly divisible by 4
except every year that is evenly divisible by 100
unless the year is also evenly divisible by 400
```
For example, 1997 is not a leap year, but 1996 is.
1900 is not a leap year, but 2000 is.
## Notes
Though our exercise adopts some very simple rules, there is more to learn!
For a delightful, four minute explanation of the whole leap year phenomenon, go watch [this youtube video][video].

# Scrabble Score
Welcome to Scrabble Score on Exercism's Dart Track.
If you need help running the tests or submitting your code, check out `HELP.md`.
## Instructions
Given a word, compute the Scrabble score for that word.
## Letter Values
You'll need these:
```text
Letter Value
A, E, I, O, U, L, N, R, S, T 1
D, G 2
B, C, M, P 3
F, H, V, W, Y 4
K 5
J, X 8
Q, Z 10
```
## Examples
"cabbage" should be scored as worth 14 points:
- 3 points for C
- 1 point for A, twice
- 3 points for B, twice
- 2 points for G
- 1 point for E
And to total:
- `3 + 2*1 + 2*3 + 2 + 1`
- = `3 + 2 + 6 + 3`
- = `5 + 9`
- = 14
## Extensions
- You can play a double or a triple letter.
- You can play a double or a triple word.

# Two Fer
Welcome to Two Fer on Exercism's Dart Track.
If you need help running the tests or submitting your code, check out `HELP.md`.
## Introduction
In some English accents, when you say "two for" quickly, it sounds like "two fer".
Two-for-one is a way of saying that if you buy one, you also get one for free.
So the phrase "two-fer" often implies a two-for-one offer.
Imagine a bakery that has a holiday offer where you can buy two cookies for the price of one ("two-fer one!").
You go for the offer and (very generously) decide to give the extra cookie to a friend.
## Instructions
Your task is to determine what you will say as you give away the extra cookie.
If your friend likes cookies, and is named Do-yun, then you will say:
```text
One for Do-yun, one for me.
```
If your friend doesn't like cookies, you give the cookie to the next person in line at the bakery.
Since you don't know their name, you will say _you_ instead.
```text
One for you, one for me.
```
Here are some examples:
|Name |Dialogue
|:-------|:------------------
|Alice |One for Alice, one for me.
|Bohdan |One for Bohdan, one for me.
| |One for you, one for me.
|Zaphod |One for Zaphod, one for me.
