Find First and Last Position of Target

Given a sorted array of integers, your task is to find the first and last positions of a target integer in the array. If the target does not exist, return [-1, -1]. If the array is [5, 7, 7, 8, 8, 10] and the target is 8, the result should be [3, 4]. Input Format: - The first line contains an integer n (1 ≤ n ≤ 1000), the number of elements in the array. - The second line contains n space-separated integers representing the array elements. - The third line contains the target integer. Output Format: - A list of two integers representing the first and last positions of the target. Example: Input: 6 5 7 7 8 8 10 8 Output: 3 4
