Refer to the raw data (table):
3A) Generate a hash table for the following values: 11, 9, 6, 28, 19, 46, 34, 14. Assume the table size is
9 and the primary hash function is h(k) = k % 9.
i) Hash table using quadratic probing
ii) Hash table with a secondary hash function of h2(k) = 7- (k%7)
3B) Demonstrate with a suitable example, any three possible ways to remove the keys and yet
maintaining the properties of a B-Tree.
3C) Differentiate between Greedy and Dynamic Programming.

The alarm does nothing while it is disarmed (‘switched off’). It canbe armed (‘switched on’) by entering a PIN on the keypad. Whenever thealarm is armed, it can be disarmed by entering the PIN on the keypad.If motion is detected while the alarm is armed, the siren should sound AND asingle SMS message sent to the police to notify them. Further motion shouldnot result in more messages being sent. If the siren is sounding, it can only bedisarmed by entering the PIN on the keypad. Once the alarm is disarmed, asingle SMS should be sent to the police to notify them.Two (active-high) input signals are provided to the controller:MOTION: Asserted while motion is detected inside the home.PIN: Asserted for a single clock cycle whenever the PIN has beencorrectly entered on the keypad.The controller must provide two (active-high) outputs:SIREN: The siren sounds while this output is asserted.POLICE: One SMS…arrow_forward
