Question
linear probing with lazy delete. Create a delete() method for LinearProbingHashST that deletes key-value pairs by setting the value to null (while leaving the key alone) and subsequently removing the pair from the table in resize.(). Choosing when to call resize is your main challenge.(). Note: If a subsequent put() action associates a new value with the key, you should overwrite the null value. Make sure that when deciding whether to enlarge or contract the table, your programme takes into account both the number of such tombstone items and the number of empty positions.

Your primary challenge is to decide when to call resize(). Note : You should overwrite the null value ifa subsequent put() operation associates a new value with the key.

- Using hash tables of a Map data structure you will write. Write your application by following the steps below: 1. Store char * (name) as key and int (number of courses taken) as value in your map. Let the hash function you use use an algorithm you specify when converting the name into an index. 2. Let the put function add the given name and the number of lessons taken to the map. If the name (key) exists on the map, replace this existing name and the number of courses taken with a new one. That is, only one unique key can be found on the map at a time. 3. The contains function checks whether the key (name) sent to it is on the map. Send 1 if available, 0 otherwise. 4. Let the Get function send the number of lessons learned for the most sent key. If the key is not present in the map, it returns -1. 5. The display function displays all key-value pairs of the map print it. 6. Search for free space linearly in case of collision.

If the student that is removed was registered, then this student should be replaced by the student who is first in the waitlist queue. If the student who is removed was on the waitlist, then they should just be removed from the waitlist. You should go directly to slot id % m rather than iterating through all the slots. public class Course { public String code; public int capacity; public SLinkedList<Student>[] studentTable; public int size; public SLinkedList<Student> waitlist; public Course(String code) { this.code = code; this.studentTable = new SLinkedList[10]; this.size = 0; this.waitlist = new SLinkedList<Student>(); this.capacity = 10; } public…arrow_forward

Include a delete() function in LinearProbingHashST that deletes a key-value pair by changing the value to null (while leaving the key in place) and then deleting the pair from the table in resize(). The most difficult decision you must make is when to use resize(). Note: If a future put() action associates a new value with the key, you should replace the null value. Make sure that while deciding whether to enlarge or shrink the table, your programme takes into consideration both the number of such tombstone items and the number of vacant places.arrow_forwardThe size of the largest linkedlist in terms of the number of nodes it contains is unknown.Is there one that you remember being really lengthy?arrow_forward
