[9]. Write the specification and implementation for a function that "squeezes" the duplicates out of sorted list. For example: x- [1,1, 3, 3, 3, 4, 5, 5, 8,9,9, 9,10] squeeze(x) printx Example Output: Original List: [1, 1,3, 3, 3, 4, 5,5,8,9,9,9,10] Squished List: [1, 3, 4, 5, 8, 9] You may design this Python 3 program any way you choose.
