Problem Statement

Given an array arr, you transform it daily based on the following rules:

  1. If an element is smaller than both its left and right neighbors, increment it by 1.
  2. If an element is larger than both its left and right neighbors, decrement it by 1.
  3. The first and last elements of the array do not change.

Continue transforming the array until no more changes occur. Return the final state of the array.
