🔗  https://leetcode.com/problems/maximum-difference-between-adjacent-elements-in-a-circular-array

题目

• 给一个循环数组 num
• 返回相邻两个数字 absolute difference 的最大值

思路

• 遍历相邻两个数组的 absolute difference，记录最大值，处理一下 circular 的边界

代码

class Solution {
public:int abs(int num) {if (num < 0) return -num;return num;}int maxAdjacentDistance(vector<int>& nums) {int ans = abs(*(nums.end() - 1) - nums[0]);for (int i = 0; i < nums.size() - 1; i++) {ans = max(ans, abs(nums[i] - nums[i+1]));}return ans;}
};
