Chapter 8, Problem 16RQE
Program Plan Intro
Linear search:
- Linear search or sequential search is the process of searching for a particular element that is present in the array one by one till the last element in the search element is found.
- The search uses a loop that iterates from the beginning till the last element to find the search element.
- The search continues for all the elements present in the array until the last element.
- The search of the target element is made after comparing it with each and every element that is present in the array.

Minimum Difference Sum Given an array of n integers, rearrange them so that the sum of the absolute differences of all adjacent elements is minimized. Then, compute the sum of those absolute differences. Example n = 5 arr = [1, 3, 3, 2, 4] If the list is rearranged as arr' = [1, 2, 3, 3, 4], the absolute differences are /1-2/ = 1, 12-3|= 1, 13- 3|=0, 13-4/= 1.
