[LeetCode] 1287. Element Appearing More Than 25% In Sorted Array 有序数组中出现次数超过25%的元素

Given an integer array sorted in non-decreasing order, there is exactly one integer in the array that occurs more than 25% of the time, return that integer. Example 1: Input: arr = [1,2,2,6,6,6,6,7,10] Output: 6 Example 2: Input: arr = [1,1] Output: 1 C

1287. 有序数组中出现次数超过25%的元素 难度 简单 | 标签 数组 Description 给你一个非递减的 有序 整数数组,已知这个数组中恰好有一个整数,它的出现次数超过数组元素总数的 25%。 请你找到并返回这个整数   示例: 输入:arr = [1,2,2,6,6,6,6,7,10] 输出:6   提示: 1 <= arr

1287. 递增的三元子序列

1287. 递增的三元子序列 给定未排序的数组,返回是否在数组中存在递增的长度为3的子序列。 完整的功能应为:如果存在i, j, k,使得arr[i] < arr[j] < arr[k],且0 ≤ i < j < k ≤ n-1,则返回true,否则返回false。您的算法应该以O(n)时间复杂度和O(1)空间复杂度运行。 样例 样例1 输

1287. Element Appearing More Than 25% In Sorted Array

问题: 给定一个递增数组,求其中出现频率>25%的元素 Example 1: Input: arr = [1,2,2,6,6,6,6,7,10] Output: 6 Constraints: 1 <= arr.length <= 10^4 0 <= arr[i] <= 10^5    解法一: 出现频率>1/4的话,这个元素可能在的位置即是: 整个数组 1/4,2/4,3/4 的位置上, 那么判断这3个
