一:线性查找(Sequential Search) 线性查找可以说是我们用的最早也会是用的最多的查找方式了.其对应的是线性数据结构,回顾一下线性数据结构,其特点是先后加入的元素是有顺序的,相邻的.而线性结构就是按其顺序挨个遍历的查找方式: for i in range(len(seq)): if seq[i] == item: print('find it in position %d'%i) break 显然,这是O(n)的时间复杂度 二:二分查找(Binary Search) 对于已经排好序

1,查找算法 常用的查找算法包括顺序查找,二分查找和哈希查找. 1.1 顺序查找(Sequential search) 顺序查找: 依次遍历列表中每一个元素,查看是否为目标元素.python实现代码如下: #无序列表 def sequentialSearch(alist,item): found = False pos=0 while not found and pos<len(alist): if alist[pos]==item: found=True else: pos = pos+1 r
