3747 Maximum Difference Between Adjacent Elements In A Circular Array

Maximum Difference Between Adjacent Elements in a Circular Array

Given a circular array nums, find the maximum absolute difference between adjacent elements.

Note: In a circular array, the first and last elements are adjacent.

 

Example 1:

Input: nums = [1,2,4]

Output: 3

Explanation:

Because nums is circular, nums[0] and nums[2] are adjacent. They have the maximum absolute difference of

4 - 1

= 3.

Example 2:

Input: nums = [-5,-10,-5]

Output: 5

Explanation:

The adjacent elements nums[0] and nums[1] have the maximum absolute difference of

-5 - (-10)

= 5.

 

Constraints:

2 <= nums.length <= 100
-100 <= nums[i] <= 100

class Solution:
    def maxAdjacentDistance(self, nums: List[int]) -> int:
        diff = 0
        for i, k in enumerate(nums):
            diff = max(diff, abs(nums[i-1] - nums[i]))
        return diff
