+│   Given a sorted array, A, with possibly duplicated elements, find the
+│   indices of the first and last occurrences of a target element, x.
+│   Return -1 if the target is not found.
+│   Example:
+│Input: A = [1,3,3,5,7,8,9,9,9,15], target = 9
+│Output: [6,8]
+│Input: A = [100, 150, 150, 153], target = 150
+│Output: [1,2]
+│Input: A = [1,2,3,4,5,6,10], target = 9
+│Output: [-1, -1]
+│
+│   Here is a function signature example:
+│class Solution:
+│  def getRange(self, arr, target):
+│    # Fill this in.
+│
+│# Test program
+│arr = [1, 2, 2, 2, 2, 3, 4, 7, 8, 8]
+│x = 2
+│print(Solution().getRange(arr, x))
+│# [1, 4]
