#3423 - Maximum Difference Between Adjacent Elements in a Circular Array

Easy • View on LeetCode • View on GitHub

Problem Description

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.

Solution

/**
 * @param {number[]} nums
 * @return {number}
 */
var maxAdjacentDistance = function(nums) {
  let result = 0;

  for (let i = 0; i < nums.length; i++) {
    const next = (i + 1) % nums.length;
    const diff = Math.abs(nums[i] - nums[next]);
    result = Math.max(result, diff);
  }

  return result;
};
