Hi, here's your problem today. This problem was recently asked by AirBNB:
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:

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]
