Array Maximal Adjacent Difference

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

array_maximal_adjacent_difference(inputArray) = 3

Solution

PYTHON

def array_maximal_adjacent_difference(inputArray):
    md = 0
    for i in range(len(inputArray) - 1):
        md = max(md, abs(inputArray[i] - inputArray[i + 1]))
    return md


print(array_maximal_adjacent_difference([9, 2, 0, 5]))

JAVASCRIPT

function arrayMaximalAdjacentDifference(inputArray) {
  let max = 0;
  for (let i = 0; i < inputArray.length - 1; i++) {
    const diff = Math.abs(inputArray[i] - inputArray[i + 1]);
    if (diff > max) {
      max = diff;
    }
  }
  return max;
}

console.log(arrayMaximalAdjacentDifference([9, 2, 0, 5]));
