- 分治是一種常見的演算法設計策略，包括分（劃分）和治（合併）兩個階段，通常基於遞迴實現。
- 判斷是否是分治演算法問題的依據包括：問題能否分解、子問題是否獨立、子問題能否合併。
- 合併排序是分治策略的典型應用，其遞迴地將陣列劃分為等長的兩個子陣列，直到只剩一個元素時開始逐層合併，從而完成排序。

# 小結
+### 重點回顧
+
- 動態規劃對問題進行分解，並透過儲存子問題的解來規避重複計算，提高計算效率。
- 不考慮時間的前提下，所有動態規劃問題都可以用回溯（暴力搜尋）進行求解，但遞迴樹中存在大量的重疊子問題，效率極低。透過引入記憶化串列，可以儲存所有計算過的子問題的解，從而保證重疊子問題只被計算一次。
- 記憶化搜尋是一種從頂至底的遞迴式解法，而與之對應的動態規劃是一種從底至頂的遞推式解法，其如同“填寫表格”一樣。由於當前狀態僅依賴某些區域性狀態，因此我們可以消除 $dp$ 表的一個維度，從而降低空間複雜度。

- 貪婪演算法通常用於解決最最佳化問題，其原理是在每個決策階段都做出區域性最優的決策，以期獲得全域性最優解。
- 貪婪演算法會迭代地做出一個又一個的貪婪選擇，每輪都將問題轉化成一個規模更小的子問題，直到問題被解決。
- 貪婪演算法不僅實現簡單，還具有很高的解題效率。相比於動態規劃，貪婪演算法的時間複雜度通常更低。

- 演算法在日常生活中無處不在，並不是遙不可及的高深知識。實際上，我們已經在不知不覺中學會了許多演算法，用以解決生活中的大小問題。
- 查字典的原理與二分搜尋演算法相一致。二分搜尋演算法體現了分而治之的重要演算法思想。
- 整理撲克的過程與插入排序演算法非常類似。插入排序演算法適合排序小型資料集。

# 小結
+### 重點回顧
+
- 本書的主要受眾是演算法初學者。如果你已有一定基礎，本書能幫助你系統回顧演算法知識，書中源程式碼也可作為“刷題工具庫”使用。
- 書中內容主要包括複雜度分析、資料結構和演算法三部分，涵蓋了該領域的大部分主題。
- 對於演算法新手，在初學階段閱讀一本入門書至關重要，可以少走許多彎路。

- 二分搜尋依賴資料的有序性，透過迴圈逐步縮減一半搜尋區間來進行查詢。它要求輸入資料有序，且僅適用於陣列或基於陣列實現的資料結構。
- 暴力搜尋透過走訪資料結構來定位資料。線性搜尋適用於陣列和鏈結串列，廣度優先搜尋和深度優先搜尋適用於圖和樹。此類演算法通用性好，無須對資料進行預處理，但時間複雜度 $O(n)$ 較高。
- 雜湊查詢、樹查詢和二分搜尋屬於高效搜尋方法，可在特定資料結構中快速定位目標元素。此類演算法效率高，時間複雜度可達 $O(\log n)$ 甚至 $O(1)$ ，但通常需要藉助額外資料結構。
