Consider a hash table of capacity 5 that uses open addressing with linear probing. This hash table uses a hash function that takes the remainder when the hash code of a string is divided by the capacity of the hash table. (Fo example, "air" hashes 0.) The hashCode method has been overridden for strings, which simply returns 0 if a string begins with 'a', 1 if it begins with 'b', etc. ** Returns 0 if a String begins with 'a', 1 if it begins with 'b', etc. */ public int hashCode() { return this.charAt(0) - 'a'; Assume that "apple", and "butter" have been inserted in this order into the hash table. "fig" is to be inserted into the hash table. a) Which array slot/index should "fig" be placed? Answer: b) What is the load factor after "fig" is inserted into the hash table? Answer:

You have two numbers represented by a linked list, where each node contains a single digit. The digits are stored in reverse order, such that the 1 's digit is at the head of the list. Write a function that adds the two numbers and returns the sum as a linked list.EXAMPLEInput: (7-> 1 -> 6) + (5 -> 9 -> 2).That is,617 + 295.Output: 2 -> 1 -> 9. That is, 912.FOLLOW UPSuppose the digits are stored in forward order. Repeat the above problem.Input: (6 -> 1 -> 7) + (2 -> 9 -> 5).That is,617 + 295.Output: 9 -> 1 -> 2. That is, 912.
Select all explicit instructions that apply to the following prompt: Implement an open addressing hash table to store a list of integers. Your task is to handle collisions using open addressing and implement basic operations such as insertion, deletion, and searching. The open addressing technique you will use is linear probing.
this is the MD5 hashing for js, how do i do something similar for C++? function hashCode(str){ md5(str);var hash = md5.create();hash.update(str);hash.hex();var hashed = hash.array();var ka ='';for(i=0;i<hashed.length;i++){ka+=String.fromCharCode(hashed[i]);}return ka;}

Consider a linked list (SLL or DLL your choice) in which, to delete anelement from the list, we simply mark that node for the deletion.Whenever the number of deleted nodes in the list exceeds the number ofnon-deleted nodes, we simply delete all nodes which were marked fordeletion. Implement the following operations for such a linked list.1. addFirst2. addLast3. delFirst4. delLast5. Delete (mark for deletion) an ith node in the list.6. display all non-deleted nodes in the list7. Size : number of non-deleted nodes in the list.8. Recall the last deleted node in the list.
Given the following Java functions, transcribe it into a Python 3 program. /*** Add a new entry with the specified key, value and hash code to* the specified bucket. It is the responsibility of this* method to resize the table if appropriate.*/void addEntry(int hash, Object key, Object value, int bucketIndex) {table[bucketIndex] = new Entry(hash, key, value, table[bucketIndex]);if (size++ >= threshold)resize(2 * table.length);}
fast please c++ Insert the elements of A in hash table H of size 10. H is a vector of int is size 10. Do not allow duplicates. Draw the table. The hash function is the number itself; f(n) = n%10
Construct a system that enables users to add and delete vehicles from an inventory system. The licence number, an eight-character string, make, model, and colour will be used to identify vehicles. Use chaining to implement your own array-based hash table.
Create a newconcrete class that implements MyMap using open addressing with quadratic probing.For simplicity, use f(key) = key % size as the hash function, where sizeis the hash-table size. Initially, the hash-table size is 6. The table size is doubledwhenever the load factor exceeds the threshold (0.5).
assume you have a HashMap class that uses a threshold of 0.75 (75%),regardless of the collision resolution mechanism used, and has an initial array size of 13. You may assume the array is resized when the current item to be added will make the load factor greater than or equal to the threshold. Recall that the load factor is the fraction of a hash map that is full. If the array is to be resized, assume the array doubles in size and adds one (2 * size + 1).Table 1 contains a list of items and their associated hash codes that were computed with somehypothetical hash function. Assume the items are added to a newly created instance of the HashMap class in the same order in which they are listed in the table. Based on this information, show what the array of the HashMap would look like after all the items have been added using both of the followinghash collision resolution techniques.1.
