十大資料結構

演算法 資料結構 程式設計 陣列是最簡單 也是使用最廣泛的資料結構。棧 佇列等其他資料結構均由陣列演變而來。下圖是乙個包含元素 1，2，3和4 的簡單陣列，陣列長度為4。每個資料元素都關聯乙個正數值，我們稱之為索引，它表明陣列中每個元素所在的位置。大部分語言將初始索引定義為零。以下是陣列的兩種型別 ...

雜湊表 也叫雜湊表,通過將關鍵碼值對映到表中的乙個位置來訪問,加快查詢的速度,對映函式也叫雜湊函式,存放記錄的陣列叫雜湊表,在對一些不常改變的資料進行操作的時候,為了加快速度,通常會採用快取技術將其載入 到記憶體中進行操作,而不直接對資料庫進行操作,如redis,雜湊表就相當於乙個簡化版redis,...
