H指数 给定一位研究者论文被引用次数的数组(被引用次数是非负整数).编写一个方法,计算出研究者的 h 指数. h 指数的定义: "一位有 h 指数的学者,代表他(她)的 N 篇论文中至多有 h 篇论文,分别被引用了至少 h 次,其余的 N - h 篇论文每篇被引用次数不多于 h 次." 示例: 输入: citations = [3,0,6,1,5] 输出: 3 解释: 给定数组表示研究者总共有 5 篇论文,每篇论文相应的被引用了 3, 0, 6, 1, 5 次. 由于研究者有 3 篇论…

刷题备忘录,for bug-free leetcode 396. Rotate Function 题意: Given an array of integers A and let n to be its length. Assume Bk to be an array obtained by rotating the array A k positions clock-wise, we define a "rotation function" F on A as follow: F(k…

刷题备忘录,for bug-free 招行面试题--求无序数组最长连续序列的长度,这里连续指的是值连续--间隔为1,并不是数值的位置连续 问题: 给出一个未排序的整数数组,找出最长的连续元素序列的长度. 如: 给出[100, 4, 200, 1, 3, 2], 最长的连续元素序列是[1, 2, 3, 4].返回它的长度:4. 你的算法必须有O(n)的时间复杂度 . 解法: 初始思路 要找连续的元素,第一反应一般是先把数组排序.但悲剧的是题目中明确要求了O(n)的时间复杂度,要做一次排序,是不能达…

Follow up for H-Index: What if the citations array is sorted in ascending order? Could you optimize your algorithm? Hint: Expected runtime complexity is in O(log n) and the input is sorted. 274. H-Index H指数 的拓展.输入的数组是有序的,让我们优化算法.提示(现在题目中没有提示了):O(logn…
