a. [5 pts] Given an array a, a, a,....am-2, a -1 Write and test function Rearrange to rearrange the array elements all even numbers appear before all the odd numbers in the modified array. If the array was Then after calling function Rearrange Array elements are: 8 12 10 46 17 155 17 b. [9 pts] Given a Single linked list of integers, write and text function Rearrange to modify the linked list such that all even numbers appear before all the odd numbers in the modified linked list. Also, keep the order of even and odd numbers same. Examples 1: Input: 17->15->8->12->10->5->4->1->7->6->NULL Output: 8->12->10->4->6->17->15->5->1->7->NULL Example 2: Input: 8->12->10->5->4->1->6->NULL Output: 8->12->10->4->6->5->1->NULL c. (6 pts) After implementing and testing the above functions, answer the following: 1. What is the space complexity of each data structure (array and linked list)? 2. Compare the time complexity to build, insert a new item at the end of the data structure, delete an item, and find an item in each data structure 3. Which data structure would you prefer to use and why
