Question 5 Suppose we have a hash table which uses linear probing which is full and needs to be expanded. What is the worst case time complexity of expanding the hash table, assuming that hash functions are O(1)? (a) (b) O (c) (d) (e) O O(1) O(log n) O(n) O(n log n) O(n^2) ✓ Your response was correct. Expanding the hash table requires rehashing/re-inserting each element. The worst case time complexity of inserting an element into a hash table is O(n), and therefore the worst case time complexity of expanding the hash table is n x O(n) = O(n^2).

Wireless Internet is becoming more valuable in today's developing countries. Since the advent of Wi-Fi, conventional networks like LANs have become mostly obsolete. Can the present state of affairs be characterised as good or bad?
Q1: Please revise the following paragraph for clarity and conciseness Due to the fact that access to internet resources is actually at the present time very easy to access in many places, electronic devices have become more and more portable and convenient, providing nearly constant (and ever more efficient) access to the Internet and a diverse range of software applications and digital media. With this ease of access, technology is playing an increasingly large role in our mental lives, it serves as a form of “extended cognition”. This situation can be viewed as a double-edged sword in a way that although it allows us to communicate, learn, and entertain ourselves, it also makes it difficult to avoid doing so even when engaging with technology is likely to distract from other ongoing activities. Notifications which are built into smartphones and other e-devices can serve as intrusion on three of our five senses, with lights, tones, and vibrations each beckoning us to extricate…
