Answer:
Program
Explanation:
class Solution(object):
def removeDuplicates(self, nums):
“””
:type nums: List[int]
:rtype: int
“””
if len(nums) == 0:
return 0
length = 1
previous = nums[0]
index = 1
for i in range(1,len(nums)):
if nums[i] != previous:
length += 1
previous = nums[i]
nums[index] = nums[i]
index+=1
return length
input_list = [1,1,2,2,2,3,3,3,3,4,5,5,5,6]
ob1 = Solution()
print(ob1.removeDuplicates(input_list))
