+## What is it?
+
+這是我為了從一個網頁開發者(自學，並且沒有任何與資工、電腦科學有關的學位)，成為一個大公司軟體工程師，持續好幾個月的讀書計畫。
+
+![Coding at the whiteboard - from HBO's Silicon Valley](https://d3j2pkmjtin6ou.cloudfront.net/coding-at-the-whiteboard-silicon-valley.png)
+
+這是為了那些**新手軟體工程師**，或者是那些想要轉換跑道，從軟體/網頁開發者轉為軟體工程師(需要資工、電腦科學的知識)的人。
+
+請注意就算你有多年的軟體/網頁開發經驗，那些著名的大型軟體公司，像是Google、Amazon、Facebook，或是Microsoft事實上把軟體/網頁開發(Software/Web Development)與軟體工程(Software Engineering)視為不同，而後者需要的是電腦科學/資訊工程的知識。
+
+如果你想成為一個可靠的工程師或者是Operation Engineer，閱讀並且學習更多這份清單中的The Optional List(裡面包含網路與資訊安全的知識)。

+## Why use it?
+
+當我開始這項計畫的時候，我不知道Stack與Heap的差別，不知道時間複雜度(Big-O)，不知道樹狀結構(Tree)，也不知道如何遍歷一個圖(Graph)。過去如果我需要寫一個排序演算法(Sorting Algorithm)，那個code一定是個災難。我過去都用程式語言中內建的資料結構(Data Structure)，對於資料結構裡面的實作方法跟原理我完全沒有任何的概念。除非我的程式碰到了"out of memory"的錯誤我才會去找解決方法，否則我從不特別去花費心思管理程式中的記憶體配置。雖然我有用過多維陣列(Multidimensional Arrays)跟關聯陣列(Associative Arrays)，但我從來沒有自己時做過資料結構。
+
+這是個遠大的計畫，或許要花上你數個月的時間。如果你對其中大部分的東西已經很熟悉的話，那麼執行這項計畫所花費的時間將減少許多。
+
+## How to use it
+
+下面每項是大綱，你需要從上到下的去理解這些大綱。
+
+我用了Github-flavored markdown語法，其中包含了可以確定完成進度的任務清單。
+
+
+**建立一個新的Branch以使用Github-flavored markdown的勾選功能。只要在[]中打x，像是: [x]**
+
+
+    Fork一個branch，並且跟隨以下的指令
+
+`git checkout -b progress`
+
+`git remote add jwasham https://github.com/jwasham/coding-interview-university`
+
+`git fetch --all`
+
+    在你完成了一些目標後，在框框中打x
+
+`git add .`
+
+`git commit -m "Marked x"`
+
+`git rebase jwasham/master`
+
+`git push --force`
+

+## About Video Resources(關於影片資源)
+
+有些影片要註冊Coursera或者Edx的課程後才能觀看，也就是所謂的MOOCs。有時候某些課程需要等待好幾個月才能註冊，這期間你無法觀看這些課程的影片。
+
+    我非常喜歡那些大學的線上課程。感謝你們幫忙加入一些免費、可隨時觀看的公開資源，像是那些線上課程的YouTube影片。

+
+在面試的coding階段，你可以選擇任何一個你擅長的程式語言。但多數大公司僅有以下選擇:
+
+- C++
+- Java
+- Python
+
+你也可以選擇以下的程式語言，但可能會有某些限制:
+
+- JavaScript
+- Ruby
+
+我之前寫過一篇關於在面試時選擇程式語言的文章:[Pick One Language for the Coding Interview](https://startupnextdoor.com/important-pick-one-language-for-the-coding-interview/)
+
+你需要非常熟練這個程式語言，並且對他非常了解。

+
+
+## 在你開始之前
+
+這份清單隨著時間越來越大。當然，這也同時代表我越來越難以掌握他的整體內容。
+
+以下是一些清單內的錯誤，希望能讓你避免這些錯誤，並且有更好的學習體驗。
+
+### 1. 你沒辦法記住所有事情
+
+我看了數小時的影片，同時也寫下了大量的筆記。但過了幾個月後，大部分的東西都消失的無影無蹤。我花了三天重新看過我的筆記，並做了小字卡幫助我複習他們。
+
+請閱讀以下的文章以免重蹈覆轍:
+
+[Retaining Computer Science Knowledge](https://startupnextdoor.com/retaining-computer-science-knowledge/).
+
+有人推薦給我的課程(但我還沒看過:( ): [Learning how to Learn](https://www.coursera.org/learn/learning-how-to-learn)
+
+### 2. 使用小字卡
+
+為了解決剛剛提到的遺忘問題，我自己寫了一個小字卡網站。網站上可以新增兩種小字卡，一般的以及程式碼。
+每一種類的小字卡都有不同的格式。
+
+這個小字卡網站在製作時便是以行動裝置優先的方式設計的，好處是無論我在何處，我都可以在我的手機與平板上複習。
+
+製作屬於自己的免費小字卡:
+
+- [Flashcards site repo](https://github.com/jwasham/computer-science-flash-cards)
+- [My flash cards database (old - 1200 cards)](https://github.com/jwasham/computer-science-flash-cards/blob/master/cards-jwasham.db):
+- [My flash cards database (new - 1800 cards)](https://github.com/jwasham/computer-science-flash-cards/blob/master/cards-jwasham-extreme.db):
+
+我的小字卡資料庫中包含了組合語言、Python的小知識、機器學習以及統計。這些內容已經超出了原本他的預設。
+
+**關於小字卡**:當你第一次知道答案後，別馬上把那張小字卡標記為已知。反覆複習這張小字卡，直到每次都能答對後才是真正學會了這個問題。反覆的動作會讓這個知識深深地烙印在你的腦海內。
+
+這裡有個替代我小字卡的網站[Anki](http://ankisrs.net/)，很多人向我推薦過他。這個網站用同一個字卡重複出現的方式讓你牢牢地記住他。
+這個網站非常容易使用，支援多平台，並且有雲端同步功能。在iOS平台上收費25美金，其他平台免費。
+
+這是我用Anki這個網站裡的格式所儲存的小字卡資料庫: https://ankiweb.net/shared/info/25173560 (感謝 [@xiewenya](https://github.com/xiewenya))
+
+### 3. 學習資料結構與演算法的同時，也要做一些Coding面試中常出現的問題
+
+把你學過的東西應用在解題上面，否則你很快就會忘了他們。這是一個過來人的經驗談。一旦你自認學會了一個主題，像是Linked List之類的，打開任何一本Coding面試問題書籍，做一些裡面有關Linked List的問題。接著繼續讀後面的主題。然後，再回頭反覆做有關Linked List、遞迴或者其他任何東西(原文為Recursion，非Recursive)的題目。但切記一定在讀這些資料結構、演算法的同時，也要實際去寫一些有關這些東西的題目。公司錄取你是為了能有即戰力能夠上戰場，而非一個紙上談兵的人。這邊我覺得還不錯的書籍和網站。更多: [Coding Question Practice](#coding-question-practice)
+
+### 4. 複習，複習，再複習
+
+我自己寫了一些有關於ASCII Code、網路OSI模型、Big-O(時間複雜度)等等的小抄。我有空的時候就會把他們拿出來看一看複習一下。
+
+打Code累了的話就休息半個小時，並且複習你的小字卡。
+
+### 5. 專注
+
+能夠干擾你，浪費你寶貴時間的東西很多。因此，專注集中精神實在很難。放點純音樂能幫上一些忙。
+
+## 這份清單沒有包含的內容
+
+以下為普遍但沒有包含在這份清單內的技術:
+
+- SQL
+- Javascript
+- HTML、CSS，以及其他前後端的技術
+
+## 每日計畫
+
+每個主題所花費的時間都不盡相同，有些只要一天，有些需要花上數天。有些主題只有單純的知識而無包含實作。
+
+每天我選擇下面其中一個主題，看跟該主題相關的影片，再用下面的程式語言實作:
+- C - 用使用了struct *或者其他東西當作參數的struct以及函數
+- C++ - 不要使用內建的東西
+- C++ - 用C++內建的東西，像是STL的Linked List，std::list。
+- Python - 使用內建的東西(為了練習Python)
+- 寫一些測試來驗證自己寫的東西是正確的，像是用assert()等簡單的方法。
+- 你也可以用Java來練習，上面只是我自己的方法。
+
+你不需要學會所有的程式語言，你只需要專精在某個程式語言 [one language for the interview](#pick-one-language-for-the-interview).
+
+為什麼要這樣寫Code?
+- 練習，練習，再練習，直到我對他產生厭惡感，並且能輕鬆無誤地寫出那些Code。(有些東西需要特別記住，像是在邊界的時候會出現問題(edge cases)，或者一些小細節)
+- 全部自己來(像是手動分配/釋放記憶體，不要依賴語言中的garbage collection的功能(除了Python或者Java))
+- 利用語言中內建的東西及工具，之後在實際工作的時候才能得心應手(畢竟我不想在工作時手刻一個Linked List)。
+
+我沒有時間做每個主題中的每個東西，但我會盡力而為。
+
+下面是我自己寫的程式碼:
+ - [C](https://github.com/jwasham/practice-c)
+ - [C++](https://github.com/jwasham/practice-cpp)
+ - [Python](https://github.com/jwasham/practice-python)
+
+ 你不需要記住每個演算法裡面的內容。
+
+ 試試看把程式碼寫在白板或者紙上而不是電腦上。接著用一些測資來測試他。最後才用電腦來驗證。
+
+ ## 先備知識
+
+- [ ] **學習C++**
+    - C語言無所不在。在你學習的過程中，幾乎任何一本書、課程，或者影片中你都能看到他的身影。
+    - [ ] [C Programming Language, Vol 2](https://www.amazon.com/Programming-Language-Brian-W-Kernighan/dp/0131103628)
+        - 這本書還滿輕薄的，但他能讓你有初步對於C語言的認識。看著這本書並且練習，你能更快地掌握C語言。理解C語言能讓你更了解程式的運作以及內部記憶體配置。

+- ### 陣列
+    - 實作一個可以自動調整大小的陣列(動態陣列vector)
+    - [ ] (動態)陣列背後原理:

+        - [Resizing arrays (video)](https://archive.org/details/0102WhatYouShouldKnow/03_01-resizableArrays.mp4)
+    - [ ] 實作動態陣列(可變、可動態調整大小的陣列)
+        - [ ] 練習在程式中用陣列以及指標，透過計算指標而存取該內容，而不是直接用索引。
+        - [ ] 直接動態生成一個新的陣列
+            - 可以生成一個int型別的陣列，但不要使用語言提供的功能
+            - 從16，或者更大的數開始寫，像是2的次方 - 16、32、64、128。
+        - [ ] size() - 陣列中元素個數
+        - [ ] capacity() - 陣列能存的最大元素個數
+        - [ ] is_empty()
+        - [ ] at(index) - 傳回該索引值的元素，附有邊界檢查(boundary check)
+        - [ ] push(item)
+        - [ ] insert(index, item) - 把元素插入該索引值，把原本在該索引值的元素往右邊移動。
+        - [ ] prepend(item) - 可以把元素插入索引值為0的地方。
+        - [ ] pop() - 移除陣列中最後一個元素，並回傳該元素的值。
+        - [ ] delete(index) - 刪除在該索引值的元素，並且把右邊剩下元素全部往左移。
+        - [ ] remove(item) - 從陣列中尋找該數值，並且移除他(就算陣列中數個地方都有這個數值)。
+        - [ ] find(item) - 從陣列中尋找該數值，並且傳回最前面找到該數值的索引值，如果沒有則傳回-1。
+        - [ ] resize(nex_capacity) // private function
+            - 當陣列已經用盡了所有容量後，把陣列的容量*2。
+            - 如果移除掉一個元素後，陣列實際大小是最大容量的1/4，則把陣列容量減半。
+        - [ ] 時間複雜度
+            - O(1) 在陣列末端插入/刪除元素
+            - O(n) 在任何地方插入/刪除元素
+        - [ ] 空間複雜度
+            - 在記憶體中的存放位置是連續的，這種儲存方式有助於存取的性能。
+            - 所需空間 = (陣列容量，>=n) * 元素所需大小，但就算結果為2n，實際上仍算成O(n)
+
+- ### Linked Lists
+    - [ ] Linked Lists背後原理:

+            - 沒有完整的code，裡面只包含了用struct實作節點的方式以及其記憶體配置。
+    - [ ] Linked List vs 陣列:

+    - [ ] [why you should avoid linked lists (video)](https://www.youtube.com/watch?v=YQs6IC-vgmo)
+    - [ ] 小心!: 你需要一些關於指標的指標(Pointer to pointer)的知識:
+        (當你回傳一個指標到函式，這個動作可能會改變指標所指向的地址)
+        這個頁面僅提供基本對於指標的指標的認識。我不推薦這個遍歷linked list的方式，因為他用的方式太過神奇，所以可讀性以及維護性並不好。
+        - [Pointers to Pointers](https://www.eskimo.com/~scs/cclass/int/sx8.html)
+    - [ ] 實作Linked list (我做了有末端指標(tail pointer)的版本以及無末端指標的版本):
+        - [ ] size() - 回傳linked list裡面的元素個數
+        - [ ] empty() - 回傳型態:bool，如果linked list為空，回傳true
+        - [ ] value_at(index) - 回傳索引值為index的元素的數值，第一個元素索引值為0，以此類推
+        - [ ] push_front(value) - 從linked list的起始點加入新的元素
+        - [ ] pop_front() - 移除第一個元素，並且回傳該元素的數值
+        - [ ] push_back(value) - 在linked list末端加入新元素
+        - [ ] pop_back() - 移除最後一個元素，並且回傳該元素的數值
+        - [ ] front() - 回傳第一個元素的數值
+        - [ ] back() - 回傳最後一個元素的數值
+        - [ ] insert(index, value) - 把新元素插入到該索引值，而新元素指向原本在該索引值的元素。
+        - [ ] erase(index) - 刪除該索引值的元素(節點)
+        - [ ] value_n_from_end(n) - 回傳從末端開始計算的第n個元素的數值
+        - [ ] reverse() - 反轉該linked list
+        - [ ] remove_value(value) - 刪除第一個為該數值的元素(意即7 2 2 1，要刪除2的話，只刪除index:1的那個2)
+    - [ ] 雙向linked List
+        - [背後原理(影片)](https://www.coursera.org/learn/data-structures/lecture/jpGKD/doubly-linked-lists)
+        - 不需實作
+
+- ### Stack(堆疊)
+    - [ ] [Stacks(影片)](https://www.coursera.org/learn/data-structures/lecture/UdKzQ/stacks)
+    - [ ] [使用Stacks先進後出(Last-In First-Out)(影片)](https://archive.org/details/0102WhatYouShouldKnow/05_01-usingStacksForLast-inFirst-out.mp4)
+    - [ ] 無須實作，可以用陣列實作，但這樣太過簡單了。
+
+- ### Queue(佇列)
+    - [ ] [使用Queues(先進先出)First-In First-Out(影片)](https://archive.org/details/0102WhatYouShouldKnow/05_03-usingQueuesForFirst-inFirst-out.mp4)
+    - [ ] [Queue(影片)](https://www.coursera.org/lecture/data-structures/queues-EShpq)
+    - [ ] [Circular buffer/FIFO](https://en.wikipedia.org/wiki/Circular_buffer)
+    - [ ] [Priority Queues(影片)](https://archive.org/details/0102WhatYouShouldKnow/05_04-priorityQueuesAndDeques.mp4)
+    - [ ] 使用linked list實作，包含末端指標(tail pointer):
+        - enqueue(value) - 在queue末端加入元素
+        - dequeue() - 刪除當時queue中最早進入的元素(意即queue中第一個元素)，並且回傳該元素的值。
+        - empty()
+        - full()
+    - [ ] 複雜度:
+        - 
+        - enqueue: O(1) (平均情況，無論對於用linked list或陣列實作的方法)
+        - dequeue: O(1) (linked list與陣列)

+    - [提示](https://github.com/jwasham/coding-interview-university/blob/master/extras/cheat%20sheets/system-design.pdf)
+    - 流程:
+        1. 了解問題與其範圍:
+            - 在面試官的幫助下定義使用情況
+            - 提供些額外功能的建議
+            - 移除面試官認為是超出範圍的東西
+            - 默認高可用度是必須的，並增加一些使用情況
+        2. 設想限制:
+            - 想想看每個月會有多少請求
+            - 想想看每秒會有多少請求(他們可能自願或者讓你自己計算)
+            - 評估讀寫比率
+            - 評估時請保持80/20法則
+            - 每秒有多少資料被寫入?
+            - 5年內總共需要的儲存空間
+            - 每秒有多少資料被讀取?
+        3. 抽象設計:
+            - 層(服務、資料、快取)
+            - 基礎:讀取平衡、通訊
+            - 初步概覽驅動整個服務的關鍵演算法
+            - 考慮會遇到的瓶頸以及解決方案

+## 解題練習
+
+現在你已經知道上面所有有關電腦科學的主題了，該是時候做些解題的練習了。
+
+**解題練習不能死記題目的解法**
+
+為什麼你需要練習解題:
+- 快速識別問題，以及如何應用正確的資料結構及演算法。
+- 蒐集問題的需求
+- 模擬面試時用你的方法闡述問題
+- 試著不要在電腦上寫程式，而是 在白板上或紙上
+- 想出該問題的時間與空間複雜度
+- 測試你的解法
+
+這裡有個很棒的入門教學，內容是如何在面試中有條不紊，並且有互動溝通地解決問題。這種能力可以從面試書籍中獲得，但我覺得這個也超讚的:[Algorithm design canvas](http://www.hiredintech.com/algorithm-design/)
+
+家裡沒有白板嗎？這很合理。但我是個奇怪的人，家裡有個大白板。沒有白板的話，可以去美術社買個大的繪圖板。你可以坐在沙發上練習。這是我的「沙發白板」。我在照片中放了一枝筆當作比例尺。如果你用筆的話，你將會希望你可以擦拭他，因為他很快就會變髒了。通常我都用鉛筆與橡皮擦。

+- [Algorithm Design Manual](http://www.amazon.com/Algorithm-Design-Manual-Steven-Skiena/dp/1849967202) (Skiena)
+    - 作為複習以及問題辨別
+    - 這本書中演算法的部分難度已經超過面試會出現的
+    - 本書分為兩個部分:
+        - 資料結構及演算法課本
+            - 優點:
+                - 跟其他演算法課本一樣是個很棒的複習素材
+                - 內含關於作者以往解決工業及學術上問題的經驗的故事
+                - 含C語言程式碼範例
+            - 缺點:
+                - 某些地方跟"Introduction to Algorithms"一樣艱深，但在某些主題，"Introduction to Algorithms"或許是更好的選擇。
+                - 第7、8、9章有點難以消化，因為某些地方並沒有解釋得很清楚，或者根本上我就是個學渣
+                - 別會錯意了，我很喜歡Skiena的教學方法以及他的風格。
+        - 演算法目錄:
+            - 這個部分是買這本書的最大誘因
+            - 我即將著手進行這部分，一旦完成這部分我會再更新上來
+        - 可以在kindle上租

+    - [勘誤表](http://www3.cs.stonybrook.edu/~skiena/algorist/book/errata)
+- [Write Great Code: Volume 1: Understanding the Machine](https://www.amazon.com/Write-Great-Code-Understanding-Machine/dp/1593270038)
+    - 這本書出版於2004年，某些程度上他有點過時了，但對於初步理解電腦是個很棒的資源
+    - 作者發明了[高階組合語言HLA](https://zh.wikipedia.org/wiki/%E9%AB%98%E9%9A%8E%E7%B5%84%E5%90%88%E8%AA%9E%E8%A8%80)，所以提到，並且舉了一些HLA的例子。裡面沒有用到很多，但都是很棒的組合語言的例子。
+    - 這些章節很值得一讀，讓你具備極佳的基礎:
+        - 第2章 - 數值表示法
+        - 第3章 - 二進位運算和位元運算
+        - 第4章 - 浮點數表示法
+        - 第5章 - 字元表示法
+        - 第6章 - 記憶體組織和存取
+        - 第7章 - 複合資料型別和記憶體
+        - 第9章 - CPU架構
+        - 第10章 - 指令集架構
+        - 第11章 - 記憶體架構與組織
+- [Introduction to Algorithms](https://www.amazon.com/Introduction-Algorithms-3rd-MIT-Press/dp/0262033844)
+    - **重要:** 讀這本書CP值不高。這本書作為複習演算法和資料結構還算滿不錯的，但它裡面沒有教你怎麼實作這些東西。你必須要能夠自己寫出很棒、有效率的解法。
+    - 也被稱為CLR，或是CLRS，因為Stein是後來才加入作者群的。
+
+- [Computer Architecture, Sixth Edition: A Quantitative Approach](https://www.amazon.com/dp/0128119055)
+    - 更豐富、更新(2017年)，但篇幅較長。
+
+- [Programming Pearls](http://www.amazon.com/Programming-Pearls-2nd-Jon-Bentley/dp/0201657880)
+    - 前幾章提供了一些解決coding問題的精妙絕倫的方法(有些很舊，甚至還用磁帶)，但那些只是導論。這是本程式設計和架構的指南。
+

+- ### 平衡樹
+    - 至少要了解一種平衡樹(並且理解怎麼實作他):
+    - "在平衡樹中，AVL和2/3樹已經有點過時了，而紅黑樹則比較流行。伸展樹(Splay tree)是一個特別有趣，能夠自我伸展的資料結構，他利用了旋轉rotation來移動任何accessed key到樹的根部。" - Skiena
+    - 在這麼多平衡樹之中，我選擇實作伸縮樹。從我曾聽過的看來，在面試時你並不需要會實作平衡搜尋樹。我看過了很多紅黑樹的程式碼。
+        - 伸縮樹:插入、搜尋、刪除函式
+        如果你最後選擇實作紅黑樹，試試看以下這些:
+        - 搜尋和插入函式，跳過刪除
+    - 我想學習更多有關B-Tree的東西，因為在大量資料的時候他運用得十分廣泛
+    - [自我平衡二元搜尋樹](https://en.wikipedia.org/wiki/Self-balancing_binary_search_tree)
+
+    - **AVL樹**
+        - 實際上:
+            從我所知，這些樹在實際上並沒有用到太多，但這些是他們可能會出現的地方:
+            AVL樹是另一個能夠在O(log n)的時間內搜尋、插入和刪除的資料結構。AVL樹比起紅黑樹更加嚴格的兩邊平衡，而這也導致了比較慢的插入和刪除，但比較快速的拿取。這對於那些只要建立一次，之後就只要取用的資料結構非常有吸引力，像是字典(或是程式字典，像是直譯器或組譯器的opcodes)
+        - [MIT AVL Trees / AVL Sort (影片)](https://www.youtube.com/watch?v=FNeL18KsWPc&list=PLUl4u3cNGP61Oq3tWYp6V_F-5jb5L2iHb&index=6)

+        - 實際上:
+            伸縮樹運用在快取、記憶體分配、路由、垃圾回收、資料壓縮、ropes(在長字串時取代string)、Windows NT(在虛擬記憶體、網路以及檔案系統)等等。

+
+    - **紅黑樹**
+        - 這些是2-3樹的解釋(請看下方)
+        - 實際上:
+            紅黑樹插入、刪除以及搜尋的時間複雜度在最糟情況下仍有一定程度的保證表現。
+            這不只讓他們在時間要求極高的應用(像是即時應用)有著很高的價值，在建構其他資料結構中也有著極高的價值。
+            舉例來說，許多在計算幾何中的資料結構都是由紅黑樹所構成的，而在Linux中用到的Completely Fair Scheduler也用到了紅黑樹。
+            在Java8中，Collection HashMap也從原本用Linked List實作，儲存特定元素的hashcode，改為用紅黑樹實作。

+
+    - **2-3搜尋樹**
+        - 實際上:
+            2-3樹在犧牲了搜尋速度下換來了相對快速的插入速度(因為高度比起AVL樹來的高)
+        - 2-3樹極少被用到，因為實作他需要用到不同的節點。因此，紅黑樹的出現機率較高。

+
+    - **2-3-4樹 (aka 2-4樹)**
+        - 實際上:
+            每個2-4樹都有相對應，有著相同資料順序的紅黑樹。2-4樹的插入以及刪除跟紅黑樹中的color-flipping以及rotation是相同的。這讓2-4樹成為了了解紅黑樹背後的
+            邏輯的重要工具，而這也是為什麼很多演算法入門課本都會在介紹紅黑樹前介紹2-4樹，即使**2-4樹在實際上並不常用到**。
