34. Find First and Last Position of Element in Sorted Array

Medium

Given an array of integers nums sorted in non-decreasing order, find the starting and ending position of a given target value.

If target is not found in the array, return [-1, -1].

You must write an algorithm with O(log n) runtime complexity.

Example 1:

Input: nums = [5,7,7,8,8,10], target = 8
Output: [3,4]

Example 2:

Input: nums = [5,7,7,8,8,10], target = 6
Output: [-1,-1]

Example 3:

Input: nums = [], target = 0
Output: [-1,-1]

Constraints:

  • 0 <= nums.length <= 105
  • -109 <= nums[i] <= 109
  • nums is a non-decreasing array.
  • -109 <= target <= 109

WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested

M1 is an arm64/v8 architecture, so that Docker will build an image with arm64/v8 architecture. In order to use Docker image in AWS EC2, which generally uses amazonlinux OS and its architecture is linux/amd64, docker image should be a linux/amd64 architecture. So when you build, you can designate image’s platform to be based as linux/amd64.

docker build --no-cache --platform=linux/amd64 -t [TAG_NAME].
