Detailed Explanation:\nInitialize Variables:\n\nmx = max(n): Finds the maximum value in the list n.\nmn = min(n): Finds the minimum value in the list n.\nst = set(n): Converts the list n to a set, which removes duplicates and allows for fast membership checks.\nCheck Divisibility:\n\nif (mx - mn) % (len(n) - 1) != 0: return False:\nThis line checks if the difference between the maximum and minimum elements (mx - mn) is evenly divisible by the number of intervals (which is len(n) - 1).\nIf not, it returns False immediately, because this means the list cannot form an arithmetic sequence.\nCalculate Step (Common Difference):\n\nstep = (mx - mn) // (len(n) - 1):\nIf the condition in step 2 is passed, it calculates the common difference (step) by dividing the difference between the maximum and minimum elements by the number of intervals.\nHandle Edge Case of All Equal Elements:\n\nif not step: return mx == mn:\nIf the calculated step is 0 (which happens when mx == mn), it checks whether all elements in the list are equal.\nIf they are, the list is arithmetic, and the function returns True.\nCheck for Missing Elements:\n\nfor i in range(mn, mx, step): if i not in st: return False:\nThis loop iterates over the expected elements in the arithmetic sequence starting from the minimum (mn), stepping by the calculated step, up to the maximum (mx).\nIf any expected element is missing in the set st, it returns False.\nReturn True:\n\nreturn True:\nIf the loop completes without finding any missing elements, the function concludes that the list n forms an arithmetic sequence and returns True.\nExample Scenarios:\nExample 1: n = [3, 6, 9, 12]\n\nmx = 12, mn = 3, step = 3\nThe function will check for the presence of [3, 6, 9, 12] and return True.\nExample 2: n = [2, 4, 6, 8, 10]\n\nmx = 10, mn = 2, step = 2\nThe function will check for the presence of [2, 4, 6, 8, 10] and return True.\nExample 3: n = [1, 2, 4]\n\nmx = 4, mn = 1, step = 1.5 (which would not be an integer)\nThe function will return False at the divisibility check.\n\n# Complexity\n- Time complexity:\n<!-- Add your time complexity here, e.g. $$O(n)$$ -->\n\n- Space complexity:\n<!-- Add your space complexity here, e.g. $$O(n)$$ -->\n\n# Code\n```\nfrom itertools import permutations\nclass Solution(object):\n    def checkArithmeticSubarrays(self, nums, l, r):\n        """\n        :type nums: List[int]\n        :type l: List[int]\n        :type r: List[int]\n        :rtype: List[bool]"""\n\n        def isArith(n):\n            mx, mn, st = max(n), min(n), set(n)\n            if (mx - mn) % (len(n) - 1) != 0:\n                return False\n            step = (mx - mn) // (len(n) - 1)\n            if not step:\n                return mx == mn\n            for i in range(mn, mx, step):\n                if i not in st:\n                    return False\n            return True\n        ans=[]\n        for start,stop in zip(l,r):\n            ans.append(isArith(nums[start:stop+1]))\n        return ans\n```
