Python simple solution
Python :\n\n\ndef minimumDifference(self, nums: List[int], k: int) -> int:\n\tif len(nums) <= 1:\n\t\treturn 0\n\n\tnums = sorted(nums)\n\tres = nums[k-1] - num
**Python :**\n\n```\ndef minimumDifference(self, nums: List[int], k: int) -> int:\n\tif len(nums) <= 1:\n\t\treturn 0\n\n\tnums = sorted(nums)\n\tres = nums[k-1] - nums[0]\n\n\tfor i in range(k, len(nums)):\n\t\tres = min(res, nums[i] - nums[i - k + 1])\n\n\treturn res\n```\n\n**Like it ? please upvote !**
