+# Accumulate
+
+Implement the `accumulate` operation, which, given a collection and an
+operation to perform on each element of the collection, returns a new
+collection containing the result of applying that operation to each element of
+the input collection.
+
+Given the collection of numbers:
+
+- 1, 2, 3, 4, 5
+
+And the operation:
+
+- square a number (`x => x * x`)
+
+Your code should be able to produce the collection of squares:
+
+- 1, 4, 9, 16, 25
+
+Check out the test suite to see the expected function signature.
+
+## Restrictions
+
+Keep your hands off that collect/map/fmap/whatchamacallit functionality
+provided by your standard library!
+Solve this one yourself using other basic tools instead.
+
+Lisp specific: it's perfectly fine to use `MAPCAR` or the equivalent,
+as this is idiomatic Lisp, not a library function.
+
+## Hints		
+This exercise requires you to write an extension method. For more information, see [this page](https://msdn.microsoft.com/en-us//library/bb383977.aspx).

+Convert a number, represented as a sequence of digits in one base, to any other base.

+## About [Positional Notation](https://en.wikipedia.org/wiki/Positional_notation)

+In positional notation, a number in base **b** can be understood as a linear
+combination of powers of **b**.
+
+The number 42, *in base 10*, means:

+# Allergies
+
+Given a person's allergy score, determine whether or not they're allergic to a given item, and their full list of allergies.
+
+An allergy test produces a single numeric score which contains the
+information about all the allergies the person has (that they were
+tested for).
+
+The list of items (and their value) that were tested are:
+
+* eggs (1)
+* peanuts (2)
+* shellfish (4)
+* strawberries (8)
+* tomatoes (16)
+* chocolate (32)
+* pollen (64)
+* cats (128)
+
+So if Tom is allergic to peanuts and chocolate, he gets a score of 34.
+
+Now, given just that score of 34, your program should be able to say:
+
+- Whether Tom is allergic to any one of those allergens listed above.
+- All the allergens Tom is allergic to.
+
+Note: a given score may include allergens **not** listed above (i.e.
+allergens that score 256, 512, 1024, etc.).  Your program should
+ignore those components of the score.  For example, if the allergy
+score is 257, your program should only report the eggs (1) allergy.
+

+# Alphametics
+
+Write a function to solve alphametics puzzles.
+
+[Alphametics](https://en.wikipedia.org/wiki/Alphametics) is a puzzle where
+letters in words are replaced with numbers.
+
+For example `SEND + MORE = MONEY`:
+
+```
+  S E N D
+  M O R E +
+-----------
+M O N E Y
+```
+
+Replacing these with valid numbers gives:
+
+```
+  9 5 6 7
+  1 0 8 5 +
+-----------
+1 0 6 5 2
+```
+
+This is correct because every letter is replaced by a different number and the
+words, translated into numbers, then make a valid sum.
+
+Each letter must represent a different digit, and the leading digit of
+a multi-digit number must not be zero.
+
+Write a function to solve alphametics puzzles.

exercises/atbash-cipher/README.md

+# Atbash Cipher
+
+Create an implementation of the atbash cipher, an ancient encryption system created in the Middle East.
+
+The Atbash cipher is a simple substitution cipher that relies on
+transposing all the letters in the alphabet such that the resulting
+alphabet is backwards. The first letter is replaced with the last
+letter, the second with the second-last, and so on.
+
+An Atbash cipher for the Latin alphabet would be as follows:
+
+```plain
+Plain:  abcdefghijklmnopqrstuvwxyz
+Cipher: zyxwvutsrqponmlkjihgfedcba
+```
+
+It is a very weak cipher because it only has one possible key, and it is
+a simple monoalphabetic substitution cipher. However, this may not have
+been an issue in the cipher's time.
+
+Ciphertext is written out in groups of fixed length, the traditional group size
+being 5 letters, and punctuation is excluded. This is to make it harder to guess
+things based on word boundaries.
+
+## Examples
+- Encoding `test` gives `gvhg`
+- Decoding `gvhg` gives `test`
+- Decoding `gsvjf rxpyi ldmul cqfnk hlevi gsvoz abwlt` gives `thequickbrownfoxjumpsoverthelazydog`

+# Bank Account
+
+Simulate a bank account supporting opening/closing, withdrawals, and deposits
+of money. Watch out for concurrent transactions!
+
+A bank account can be accessed in multiple ways. Clients can make
+deposits and withdrawals using the internet, mobile phones, etc. Shops
+can charge against the account.
+
+Create an account that can be accessed from multiple threads/processes
+(terminology depends on your programming language).
+
+It should be possible to close an account; operations against a closed
+account must fail.
+
+## Instructions
+
+Run the test file, and fix each of the errors in turn. When you get the
+first test to pass, go to the first pending or skipped test, and make
+that pass as well. When all of the tests are passing, feel free to
+submit.
+
+Remember that passing code is just the first step. The goal is to work
+towards a solution that is as readable and expressive as you can make
+it.
+
+Have fun!
+
+## Hints
+This exercise requires you to handle data related to currency and money. A normal approuch is to use the [Decimal](https://msdn.microsoft.com/en-US/library/system.decimal.aspx) struct to store currency values. 
+Note though that you then only store the numeric value of a currency.
