Q2 - 25 pts) For this question, you will explore the tradeoff between the average number of comparisons for a successful search of an element in a hash table vs. the load imbalance index. It is logical to expect that as the hash table size (the size of the array of linked lists representing the hash table) grows, the length of each of the linked lists reduces: as a result, the number of comparisons that would be needed to search...
