[LeetCode] 34. Find First and Last Position of Element in Sorted Array 在排序数组中查找元素的第一个和最后一个位置 Given an array of integersnumssorted in non-decreasing order, find the starting and ending position of a giventargetvalue. Iftargetis not found in the array, return[-1, -1]...
LeetCode刷题系列—34. Find First and Last Position of Element in Sorted Array 1.题目描述 英文版: Given an array of integers nums sorted in ascending order, find the starting and ending position of a given target value. Your algorithm's runtime complexity must be in the order of O(log ...
LeetCode34. Find First and Last Position of Element in Sorted Array JonesM - LeetCodeleetcode.com/problems/find-first-and-last-position-of-element-in-sorted-array/ 解题思路 1. 二分找元素,双指针找区间 class Solution { public: vector<int> searchRange(vector<int>& nums, int target) {...
Given an array of integers nums sorted in ascending order, find the starting and ending position of a given target value. Your algorithm’s runtime complexity must be in the order of O(log n). If the target is not found in the array, return [-1, -1]. ...
输出:[-1,-1] 示例3: 输入:nums = [], target = 0 输出:[-1,-1] 来源:力扣(LeetCode) 链接:https://leetcode-cn.com/problems/find-first-and-last-position-of-element-in-sorted-array python class Solution: def searchRange(self, nums: [int], target: int) -> [int]: ...
image.png 由于题目要求的Time Complexity O(log N),那么肯定是二分法。 二分法的基本原则,根据middle与target的比较决定如何移动start&end。 iftarget<middle,move end==>end=middleiftarget>middle,move start==>start=middle 但本题的关键在于出现了重复,需要找重复target的startIndexandendIndex, 那么现在问题是当...
Output: [-1,-1] 也是一道典型的二分法题目,思路是通过二分法思想分别找到第一个插入的位置和第二个插入的位置。 时间O(log n) 空间O(1) /** * @param {number[]} nums * @param {number} target * @return {number[]} */ var searchRange = function(nums, target) { ...
Given an array of integers nums sorted in ascending order, find the starting and ending position of a given target value. Your algorithm's runtime complexity must be in the order of O(log n). If the target is not found in the array, return [-1, -1]. ...
