3423. 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.

def maxAdjacentDistance(self, nums: List[int]) -> int:
	maxe = 0 
	for i in range(len(nums)-1):
		sub = abs(nums[i] - nums[i+1])
		if sub > maxe:
			maxe = sub
	sub = abs(nums[-1] - nums[0])
	if sub > maxe:
		maxe = sub
	return maxe
