[Leetcode][python]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 题目大意 给定一个按照升序排列的整数数组 nums,和一个目标值 target。找出给定目标值在数组中的开始位置和结束位置。 你的算法时间复杂度必须是 O(log n) 级别。
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) { ...
