Given an array of integers, find the maximal absolute difference between any two of its adjacent elements.

Example

For inputArray = [2, 4, 1, 0], the output should be arrayMaximalAdjacentDifference(inputArray) = 3.

For inputArray = [2, 9, 1, 0], the output should be arrayMaximalAdjacentDifference(inputArray) = 8.

Hints

• Math.abs()

Input/Output

• [time limit] 4000ms (js)
• [input] array.integer inputArray

Guaranteed constraints:

3 ≤ inputArray.length ≤ 10,

-15 ≤ inputArray[i] ≤ 15.

• [output] integer

The maximal absolute difference.
