A peak element is an element that is greater than its neighbors. Given an input array where num[i] ≠ num[i+1], find a peak element and return its index. The array may contain multiple peaks, in that case return the index to any one of the peaks is fine. You may imagine that nu...
For example, in array[1, 2, 3, 1], 3 is a peak element and your function should return the index number 2. 解题思路1: 直接想到的思路是,由于num[-1]是负无穷,因此num[0]对于它的previous neighbor是上升的,只需从num头开始遍历,找到第一个num[i] > num[i + 1]的数,那么i就是Peak Eleme...
A peak element is an element that is greater than its neighbors. Given an input array wherenum[i]≠ num[i+1], find a peak element and return its index. The array may contain multiple peaks, in that case return the index to any one of the peaks is fine. You may imagine thatnum[-...
Output:The peak element is 10 Practice this problem A naive solution would be to test all elements for peak by running a linear search on the array and return the greater element than its neighbors. Two special cases needs to be handled. If the array is sorted in descending order, its pe...
Find Peak Element A peak element is an element that is greater than its neighbors. Given an input array wherenum[i] ≠ num[i+1], find a peak element and return its index. The array may contain multiple peaks, in that case return the index to any one of the peaks is fine. ...
Given an integer array nums, find a peak element, and return its index. If the array contains multiple peaks, return the index toany of the peaks. You may imagine that nums[-1] = nums[n] = -∞. You must write an algorithm that runs inO(log n) time. ...
162. Find Peak Element 信息门下皮卡丘 佛系皮卡丘分界点很多找其中任意一个的情况。例如findPeak, 它的peak(波)可以有很多,peak(波)之间也没有性质能把它们区分出来,乍看上去不适用于二分。但题目要求并不是找特定的peak,而是找到任意一个就行了。因此给定的数列可以划分成俩坨,前面那坨满足严格上升(题有说前...
