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) {...
时间O(log n) 空间O(1) /** * @param {number[]} nums * @param {number} target * @return {number[]} */ var searchRange = function(nums, target) { // corner case if (nums === null || nums.length === 0) { return [-1, -1]; ...
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]. ...
题目 给定一个排序数组, 找出某个数字第一次出现的最后一次出现的位置.找不到就输出-1; 思路1 时间复杂度 O(n). 从头到尾遍历一次, 找到第一次出现的位置, 再向后找...
3. Code: 1/2 2/2 3.1. Explaination of the Code: Initialization Check: Check if not nums to immediately return [-1, -1] if the input array is empty. Validity Check: Ensure start and end are within the valid bounds of the array and that nums[start] and nums[end] actually match...
Find the minimum element. The array may contain duplicates. Example 1: Input: [1,3,5] Output: 1 1. 2. Example 2: Input: [2,2,2,0,1] Output: 0 1. 2. Note: This is a follow up problem to Find Minimum in Rotated Sorted Array. ...
