「無論你想在程式設計面試中獲得優勢，想創造美麗的數學藝術，還是頑固地非得理解這個概念的有趣特性，這本書都將成為你深入遞迴這個兔子洞的指南（兔子洞裡還有兔子洞）。」遞迴程式設計技術可以產生優雅的程式解決方案，然而更常見的是，它讓程式設計師感到困惑。這並不代表程式設計師可以（或應該）忽略遞迴；儘管遞迴以具有挑戰性而聞名，但它是一個重要的電腦科學主題，並且可以對程式設計本身產生敏銳的洞察力。至少，了解遞迴可以幫助你順利通過程式設計工作面試。如果你是對電腦科學感興趣的學生，遞迴是你要理解許多流行演算法所必須克服的必要障礙。如果你是程式設計訓練營的畢業生或自學而成的程式設計師，並且順利跳過了更具理論性的電腦科學主題，但在「白板程式設計面試」中肯定還是會遇到遞迴問題。如果你是一位經驗豐富的軟體工程師，以前從未接觸過遞迴演算法，你可能會發現遞迴是你知識中一塊尷尬的缺口。❑ 本書目標讀者本書適合那些對遞迴演算法感到恐懼或感興趣的人。對於新手程式設計師或電腦科學系的大一新生來說，遞迴主題就像難以理解的黑魔法一樣。大多數遞迴課程都很難理解，使得這個主題不但讓人覺得挫敗，甚至令人心生恐懼。對於這些讀者來說，這本書的直接解釋和充足的例子應該能幫助他們最終理解這個主題。閱讀本書的唯一先決條件是具備 Python 或 JavaScript 程式語言的基本程式設計經驗，因為各章的程式碼範例使用了這兩種語言。本書的程式已被精簡到核心的基本結構； 如果你知道如何呼叫和建立函數，以及理解全域變數和局部變數之間的區別，那麼你就足以應付這些程式設計範例了。本書使用 Python 和 JavaScript 範例來教授遞迴的基礎知識，揭示了遞迴的教學方法，並闡明了所有遞迴演算法的基本原理。你將學習何時使用遞迴函數（最重要的是，何時不使用它們），如何實現工作面試中經常提到的經典遞迴演算法，以及遞迴技術如何幫助解決有關樹走訪、組合學等等許許多多的問題，以及其他棘手的話題。這個以專案為主的指南包含了完整的、可運行的程式，將能幫助你學習：☑︎ 遞迴函數如何使用呼叫堆疊，這是一種在遞迴課程中幾乎從未討論過的關鍵資料結構☑︎ 「頭尾」與「信仰飛躍」技巧如何簡化遞迴函數的編寫☑︎ 如何使用遞迴為你的檔案系統編寫自訂搜尋腳本、繪製碎形藝術、生成迷宮等☑︎ 優化和記憶如何使遞迴演算法更有效率

An anthology of vibrant new stories woven into the larger tapestry of the hit Netflix series! Discover the hidden stories from Hawkins, Indiana.On the surface, Hawkins, Indiana seems like the kind of town where nothing too out of the ordinary ever happens, but in the fall of ’83 two hunters head out into the woods with their rifles and a six-pack, and find themselves the prey of a nightmarish beast. When Barb Holland goes missing, Murray Bauman is on the case if only he can look past his own suspicious mind to solve the case. Robin Buckley’s school film project gives her a chance to work with her secret crush, but does it only make it harder to come to terms with her feelings? And when pumpkins start inexplicably rotting, the feud between two farm families reaches a boiling point.Joining Houser on her visit to Hawkins are artist Caio Filipe (Stranger Things: Summer Special, Nightwing), Sunando C (End After End), Giorgia Gio Esposito (Lunar Room, Dr. Who) colorist Dan Jackson (The Strai

From the founder of Wikipedia, a sweeping reflection on the global crisis of credibility and knowledge, revealing “the rules of trust” that transformed Wikipedia from a scrappy experiment into a global utility used by billions of people—and how those rules can help others build things that lastFrom the beginning, people predicted Wikipedia’s demise. Instead, this global experiment in sharing knowledge and expertise online has become part of the fabric of modern, connected life. Today, every month, people view Wikipedia 11 billion times—just in the English language. The Internet’s encyclopedia has become a global utility, like water or electricity, and we rarely pause to consider the extraordinary fact of its existence.Long before it became the biggest collection of knowledge in the history of the world, Wikipedia had to overcome its greatest challenge: getting strangers on the Internet to trust each other. They had to trust that others would not be abusive or uncivil. They had to trust
