Hiking Cost John, an avid hiker, wants to go on a hiking trip across a series of trails with varying difficulty levels. The difficulty levels of the trails are given in an array A of size N . John's objective is to start at the first trail, hike through all the trails, and then return to the starting trail. The cost of the trip is calculated as follows: The cost of shifting from one trail to another is determined by the absolute difference in difficulty levels between the current trail and the trail John shifts to.
