Array Maximal Adjacement Difference

Python Array Maximal Adjacement Difference

def array_maximal_adjacent_difference(a: list[int]) -> int:
    diff = 0
    for i in range(1, len(a) - 1):
        diff = max(diff, abs(a[i] - a[i - 1]), abs(a[i] - a[i + 1]))
    return diff

This checks the gap between each pair of neighbors and returns the largest difference.
