 ## Key Learnings
 
 - Lists are collections.
-- Lists can be created using `list` or by using a single quote.
+- Lists can be created using [`list`][list] or by using a single quote.
 - Clojure will try to evaluate lists, treating the first item as a function.
 - Core functions:
-  - `cons` returns a list with the new item added to beginning.
-  - `first` returns the first item from a list.
-  - `rest` returns the list without the first item.
-  - `count` returns the number of items in the list.
-  - `conj` returns a list with items appended in it.
+  - [`first`][first] returns the first item in the list.
+  - [`rest`][rest] returns a list of all items of the list except the first.
+  - [`count`][count] returns the number of items in the list.
+  - [`conj`][conj] adds one or more items to the beginning of the list.

 # Instructions
 
-In this exercise, you'll be implementing the quest logic for a new RPG game a friend is developing. The game's main character is Annalyn, a brave girl with a fierce and loyal pet dog. Unfortunately, disaster strikes, as her best friend was kidnapped while searching for berries in the forest. Annalyn will try to find and free her best friend, optionally taking her dog with her on this quest.
+In this exercise, you'll implement the quest logic for a new RPG game that a friend is developing.
+The game's main character is Annalyn, a brave girl with a fierce and loyal pet dog.
+Unfortunately, disaster strikes: her best friend was kidnapped while searching for berries in the forest.
+Annalyn will try to find and rescue her friend, optionally taking her dog along on the quest.
 
-After some time spent following her best friend's trail, she finds the camp in which her best friend is imprisoned. It turns out there are two kidnappers: a mighty knight and a cunning archer.
+After some time spent following the trail, Annalyn discovers the camp where her friend is imprisoned.
+It turns out there are two kidnappers: a mighty knight and a cunning archer.
 
 Having found the kidnappers, Annalyn considers which of the following actions she can engage in:
 
-- Fast attack: a fast attack can be made if the knight is sleeping, as it takes time for him to get his armor on, so he will be vulnerable.
-- Spy: the group can be spied upon if at least one of them is awake. Otherwise, spying is a waste of time.
-- Signal prisoner: the prisoner can be signalled using bird sounds if the prisoner is awake and the archer is sleeping, as archers are trained in bird signaling so they could intercept the message.
-- _Free prisoner_: Annalyn can try sneaking into the camp to free the prisoner.
-  This is a risky thing to do and can only succeed in one of two ways:
-  - If Annalyn has her pet dog with her she can rescue the prisoner if the archer is asleep.

     The knight is scared of the dog and the archer will not have time to get ready before Annalyn and the prisoner can escape.
-  - If Annalyn does not have her dog then she and the prisoner must be very sneaky!
-    Annalyn can free the prisoner if the prisoner is awake and the knight and archer are both sleeping, but if the prisoner is sleeping they can't be rescued: the prisoner would be startled by Annalyn's sudden appearance and wake up the knight and archer.
+  - If Annalyn does not have her pet dog, then she and the prisoner must be very sneaky!
+    Annalyn can free the prisoner if the prisoner is awake and both the knight and archer are sleeping.
+    However, if the prisoner is sleeping, they can't be rescued, as the prisoner would be startled by Annalyn's sudden appearance and wake up the knight and archer.
 
-You have four tasks: to implement the logic for determining if the above actions are available based on the state of the three characters found in the forest and whether Annalyn's pet dog is present or not.

 # Instructions
 
-A complex number is a number in the form `a + b * i` where `a` and `b` are real and `i` satisfies `i^2 = -1`.
+A **complex number** is expressed in the form `z = a + b * i`, where:
 
-`a` is called the real part and `b` is called the imaginary part of `z`.
-The conjugate of the number `a + b * i` is the number `a - b * i`.
-The absolute value of a complex number `z = a + b * i` is a real number `|z| = sqrt(a^2 + b^2)`. The square of the absolute value `|z|^2` is the result of multiplication of `z` by its complex conjugate.
+- `a` is the **real part** (a real number),
 
-The sum/difference of two complex numbers involves adding/subtracting their real and imaginary parts separately:
-`(a + i * b) + (c + i * d) = (a + c) + (b + d) * i`,
-`(a + i * b) - (c + i * d) = (a - c) + (b - d) * i`.
+- `b` is the **imaginary part** (also a real number), and
 
-Multiplication result is by definition
-`(a + i * b) * (c + i * d) = (a * c - b * d) + (b * c + a * d) * i`.
+- `i` is the **imaginary unit** satisfying `i^2 = -1`.
 
-The reciprocal of a non-zero complex number is
-`1 / (a + i * b) = a/(a^2 + b^2) - b/(a^2 + b^2) * i`.
+## Operations on Complex Numbers
 
-Dividing a complex number `a + i * b` by another `c + i * d` gives:
-`(a + i * b) / (c + i * d) = (a * c + b * d)/(c^2 + d^2) + (b * c - a * d)/(c^2 + d^2) * i`.
+### Conjugate
 
-Raising e to a complex exponent can be expressed as `e^(a + i * b) = e^a * e^(i * b)`, the last term of which is given by Euler's formula `e^(i * b) = cos(b) + i * sin(b)`.
+The conjugate of the complex number `z = a + b * i` is given by:
 
-Implement the following operations:
+```text
+zc = a - b * i
+```
 
-- addition, subtraction, multiplication and division of two complex numbers,
-- conjugate, absolute value, exponent of a given complex number.
+### Absolute Value
 
-Assume the programming language you are using does not have an implementation of complex numbers.
+The absolute value (or modulus) of `z` is defined as:
+
+```text
+|z| = sqrt(a^2 + b^2)
+```
+
+The square of the absolute value is computed as the product of `z` and its conjugate `zc`:
+
+```text
+|z|^2 = z * zc = a^2 + b^2
+```
+
+### Addition
+
+The sum of two complex numbers `z1 = a + b * i` and `z2 = c + d * i` is computed by adding their real and imaginary parts separately:
+
+```text
+z1 + z2 = (a + b * i) + (c + d * i)
+        = (a + c) + (b + d) * i
+```
+
+### Subtraction
+
+The difference of two complex numbers is obtained by subtracting their respective parts:
+
+```text
+z1 - z2 = (a + b * i) - (c + d * i)
+        = (a - c) + (b - d) * i
+```
+
+### Multiplication
+
+The product of two complex numbers is defined as:
+
+```text
+z1 * z2 = (a + b * i) * (c + d * i)
+        = (a * c - b * d) + (b * c + a * d) * i
+```
+
+### Reciprocal
+
+The reciprocal of a non-zero complex number is given by:
+
+```text
+1 / z = 1 / (a + b * i)
+      = a / (a^2 + b^2) - b / (a^2 + b^2) * i
+```
+
+### Division
+
+The division of one complex number by another is given by:
+
+```text
+z1 / z2 = z1 * (1 / z2)
+        = (a + b * i) / (c + d * i)
+        = (a * c + b * d) / (c^2 + d^2) + (b * c - a * d) / (c^2 + d^2) * i
+```
+
+### Exponentiation
+
+Raising _e_ (the base of the natural logarithm) to a complex exponent can be expressed using Euler's formula:
+
+```text
+e^(a + b * i) = e^a * e^(b * i)
+              = e^a * (cos(b) + i * sin(b))
+```
+
+## Implementation Requirements
+
+Given that you should not use built-in support for complex numbers, implement the following operations:
+
+- **addition** of two complex numbers
+- **subtraction** of two complex numbers
+- **multiplication** of two complex numbers
+- **division** of two complex numbers
+- **conjugate** of a complex number
+- **absolute value** of a complex number
+- **exponentiation** of _e_ (the base of the natural logarithm) to a complex number

-The instructions are synced with a shared repository to ensure consistency across all language tracks.
-For this exercise in the Clojure track, assume both the input and output are vectors.
-As a stretch goal, consider how you could implement the solution without using lists anywhere in your code.
-Also, think about the efficiency of your program.
-
-It is important not to reuse existing Clojure built-in functions with similar functionality, as doing so would diminish the intended learning value of the exercise.
-Key functions from the **clojure.core** namespace to avoid include `into`, `concat`, `cat`, `lazy-cat`, `mapcat`, `flatten`, `filter`, `filterv`, `remove`, `count`, `map`, `mapv`, `reduce`, `transduce`, `reverse`, and `rseq`.
-
-### Optional goals
-
-Try to pass the tests by devising a solution that assumes both the input and output are lists instead of vectors.
-The test suite does not need to be modified.
-This time, consider how you could implement the solution without using vectors anywhere in your code.
-
-If you decide to publish this solution, be sure to include a comment indicating that it addresses the optional goal of using lists. Don't forget to update the docstrings!

+## Appendix
+
+~~~~exercism/note
+The instructions above are synchronized with a shared repository to ensure consistency across all language tracks.
+This appendix provides additional clarification or modifies the instructions as needed to better align with the goals of the Clojure track.
+~~~~
+
+For this exercise in the Clojure track, **assume both the input and output are vectors**, as indicated by the tests.
+As a stretch goal, consider how to implement an approach that does not use lists for intermediate steps.
+
+It is important not to reuse existing Clojure built-in functions with similar functionality, as doing so would diminish the intended learning value of the exercise.
+Key functions from the `clojure.core` namespace to avoid include `into`, `concat`, `cat`, `lazy-cat`, `mapcat`, `flatten`, `filter`, `filterv`, `remove`, `count`, `map`, `mapv`, `reduce`, `transduce`, `reverse`, and `rseq`.
+
+### Optional goals
+
+The optional goal is for those who want an extra challenge and is designed with the expectation that you've already completed the main goal.
+
+Try to pass the tests by devising an approach that assumes:
+
+* Both the input and output are lists instead of vectors.
+  Note that, as usual, the tests do not need to be modified.
+* Vectors cannot be used for intermediate steps.

+# Description
+
+A Pythagorean triplet is a set of three natural numbers, {a, b, c}, for which,
+
+```text
+a² + b² = c²
+```
+
+and such that,
+
+```text
+a < b < c
+```
+
+For example,
+
+```text
+3² + 4² = 5².
+```
+
+Given an input integer N, find all Pythagorean triplets for which `a + b + c = N`.
+
+For example, with N = 1000, there is exactly one Pythagorean triplet for which `a + b + c = 1000`: `{200, 375, 425}`.

+# Introduction
+
+You are an accomplished problem-solver, known for your ability to tackle the most challenging mathematical puzzles.
+One evening, you receive an urgent letter from an inventor called the Triangle Tinkerer, who is working on a groundbreaking new project.
+The letter reads:
+
+> Dear Mathematician,
+>
+> I need your help.
+> I am designing a device that relies on the unique properties of Pythagorean triplets — sets of three integers that satisfy the equation a² + b² = c².
+> This device will revolutionize navigation, but for it to work, I must program it with every possible triplet where the sum of a, b, and c equals a specific number, N.
+> Calculating these triplets by hand would take me years, but I hear you are more than up to the task.
+>
+> Time is of the essence.
+> The future of my invention — and perhaps even the future of mathematical innovation — rests on your ability to solve this problem.
+
+Motivated by the importance of the task, you set out to find all Pythagorean triplets that satisfy the condition.
+Your work could have far-reaching implications, unlocking new possibilities in science and engineering.
+Can you rise to the challenge and make history?
