Find First and Last Position of Element in Sorted
Given an array of integers nums sorted in ascending order, find the starting and ending position of a given target value. [#34]
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] .
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]
Search Insert Position
Given a sorted array and a target value, return the index if the target is found. If not, return the index where it would be if it were inserted in order.
You may assume no duplicates in the array. [#35]
Example: Input: [1,3,5,6], 5 Output: 2 Input: [1,3,5,6], 2 Output: 1 Input: [1,3,5,6], 7 Output: 4 Input: [1,3,5,6], 0 Output: 0
