Describe how to perform a removal from a hash table that uses linear probing to resolve collisions. What is its worst-case time complexity?
Homework Answers
method to perform a removal from a hash table that uses linear
probing to resolve collisions:(using additional array called
flag)
-first find hashcode(or index given by hash function)
-then probe the array, starting from the index given by hash
function, until a element to be deleted is found or the value at
this index in flag array is 0
-in each iteration update index i: by (i+1)%size of hash
table
-if element is found then set value at current index to null, and
upta flag value at current index to 2 and decrease hash table
capacity
worst case complexity would be :O(n)//where n is the size of hash table

Separate Chaining A hash table of size 7 uses separate chaining to resolve collisions. A polynomial hash function where a 33 is used. Sketch the table's contents after the following words have been added in the exact order shown: find, edge, body, race, plan, beat, they You may find it useful to create a list of lowercase letters and their ASCII numeric value.

Python: Write a program that inserts numbers from a file into a linear probing hash table and records the amount of collisions that occur after each insertion. Hash Table size is 191, so 100 random numbers are to be inserted to the table to collect number of collisions.

IN C++ Create a student hash table that contains information, studentID (int), name (string), marks_oop345 (float). The size of hash table is equal to the number of students in the class. Use linear probing in case of collisions. Perform insertion, deletion, display and search operations.

#3 [3 points] Sketch a hash table of size N=11, where the hash function is hash(key) = key mod N and quadratic probing is used to resolve collisions, after the following elements are inserted: 20, 42, 45, 49, 62, 72, 95. The probes are based on this equation: (H+c1∗i+c2∗i2)mod(N) and c1=1, c2=1. If direct hashing was used to store the same elements as the previous problems (20, 42, 45, 49, 62, 72, 95), what should be the minimum size of...

For a linear probing hash table in C++ what foes into my HashLin.hpp, HashLin.cpp, and Main.cpp files. I am not really sure how all the different files work together. Also, once I have to code finished and need in input data from a file how do I do that? Any help would be great!!!

True or False? 1. Duplicate hash codes create collisions. 2. In open addressing with linear probing, a successful search for an entry that corresponds to a given search key could potentially follow a different probe sequence used to add the entry to the hash table. 3. Completely balance binary trees are not necessarily full. 4. A preorder traversal of a binary tree is an example of a depth-first traversal.

6. A hash table has size 7, uses quadratic probing (f(i) = 1), and has hash function h(2) = 2%7. (Recall, % is the Java "mod" function.) Draw the contents of the hash table after the following sequence of insertions: insert 0, insert 7, insert 14, insert 21. The hash table is initially empty.
