所以综合⽽⾔⼆叉搜索树增删查改时间复杂度为: O(N) 那么这样的效率显然是⽆法满⾜我们需求的,我们后续课程需要继续讲解⼆叉搜索树的变形,平衡⼆ 叉搜索树AVL树和红⿊树,才能适⽤于我们在内存中存储和搜索数据。 另外需要说明的是,⼆分查找也可以实现 O(logN) 级别的查找效率,但是⼆分查找有...

二分法检索(binary search)(又名二进制搜索) 定义: 二分法检索的基本思想是设字典中的元素从小到大有序地存放在数组(array)中。首先将给定值key与字典中间位置上元素的关键码(key)比较,如果相等,则检索成功;否则,若key小,则在字典前半部分中继续进行二分法检索;若key大,则在字典后半部分中继续进行二分法检索。这样...

Binary Search Algorithm: In this tutorial, we will learn about the binary search algorithm, and it's time complexity in detail and then, implemented it in both C & C++. As a follow up there are several use cases or variations of binary search. By Radib Kar Last updated : August 14,...
