Binary Search(Easy,二分搜索) 题目描述: For a given sorted array (ascending order) and atargetnumber, find the first index of this number inO(log n)time complexity. If the target number does not exist in the array, return-1. 样例:If the array is[1, 2, 3, 3, 4, 5, 10], for ...
与之类似的例子还有:LeetCode 744等,都是Easy级别的题目,简单的使用二分查找左边界的模板就行了,大家可以自行练习。 当然,除了这种显而易见的题目,对于一些变体,我们也应该要有能力去分辨,比如说这一题:LeetCode 658。 实战4:Find Minimum in Rotated Sorted Array leetcode 原题:https://leetcode.com/proble...

The above problems are quite easy to solve, because they already give us the array to be searched. We'd know that we should use binary search to solve them at first glance. However,more often are the situations where the search space and search target are not so readily avail...

When you encounter a problem which you think could be solved by applying binary search, you need some way of proving it will work. I will now present another level of abstraction which will allow us to solve more problems, make proving binary search solutions very easy and also help implemen...
Convert Sorted Array to Binary Search Tree (如有侵权,请联系作者删除) Easy 题意 给定一个升序的序列,将它转化为平衡二叉树。 平衡二叉树顾名思义,是指二叉树的任意两个子树的深度差不超过1. 题解 这一题当中我们要生成二叉搜索树了,而且还需要是平衡的。看起来似乎很难下手,但是其实很简单,有一个性质我...
