I almost exclusive see template II used for this question, I tried doing it with template III but don\'t really now how. \n\nDoes someone know the solution using template III?\n\nTemplate II:\n\n```\ndef findClosestElements(self, A, k, x):\n        left, right = 0, len(A) - k\n        while left < right:\n            mid = (left + right) / 2\n            if x - A[mid] > A[mid + k] - x:\n                left = mid + 1\n            else:\n                right = mid\n        return A[left:left + k]\n```\n
