【算法训练-二分查找四】【模拟二分】X的平方根

废话不多说，喊一句号子鼓励自己：程序员永不失业，程序员走向架构！本篇Blog的主题是【二分查找】，使用【数组】这个基本的数据结构来实现，这个高频题的站点是：CodeTop，筛选条件为：目标公司+最近一年+出现频率排序，由高到低的去牛客TOP101去找，只有两个地方都出现过才做这道题（CodeTop本身汇聚了LeetCode的来源），确保刷的题都是高频要面试考的题。m明确标题后，附上题目链接，后期....

【算法专题突破】二分查找 - x 的平方根（18）

1. 题目解析题目链接：69. x 的平方根 - 力扣（LeetCode）这道题就是求算数平方根，要注意的点是他只需要保留整数部分，小数部分会舍去2. 算法原理我们确定好一个区间 1 ~ x，数字 x 的算数平方根一定在这里面，最简单的思路就是用暴力解法每个都遍历一遍找出来，实际上，在这样一个有序的数组里面，我们可以使用二分查找来优化代码：我们每次取中点 mid当 mid * mid <=....
