Solution
This problem can be solved using Python. Here is a step-by-step guide on how to implement a hash table with linear probing:
- First, define a class for the hash table. This class will have methods for inserting keys, resolving collisions using linear probing, and displaying the keys and their corresponding indices.
class HashTable:
def __init__(self, size):
self.size = size
self.table = [None]*size
self.keys = []
def insert(self, key):
index = key % self.size
if self.table[index] is None:
self.table[index] = key
self.keys.append((index, key))
else:
self.linear_probing(index, key)
def linear_probing(self, index, key):
for i in range(index+1, self.size):
if self.table[i] is None:
self.table[i] = key
self.keys.append((i, key))
return
for i in range(0, index):
if self.table[i] is None:
self.table[i] = key
self.keys.append((i, key))
return
def display(self):
self.keys.sort()
for key in self.keys:
print(f"index: {key[0]}, value: {key[1]}")
- Next, get the size of the hash table and the keys to be inserted from the user.
size = int(input())
n = int(input())
keys = list(map(int, input().split()))
- Create an instance of the HashTable class and insert the keys into the hash table.
hash_table = HashTable(size)
for key in keys:
hash_table.insert(key)
- Finally, display the keys and their corresponding indices.
hash_table.display()
This program will take a series of integers as input, hash them into a hash table, resolve any collisions using linear probing, and then display the keys and their corresponding indices in ascending order of their original insertion.

Suppose we want to store items a, b, c, d, e, f, g, whose keys are:a.key=23b.key=7c.key=54d.key=21e.key=12f.key=42g.key=39We want to store them in a hash table of size 7 implemented with a dynamic array A, using the hash function h(k) = k mod 7, by handling collisions using chains.Start with the array A being of size 7, with all entries initialised to None (case-sensitive), and insert the items above in order (a, b, c, d, e, f, and then g). Fill the blanks with the contents of each entry: if there is only one item in A[ i ], then just write the name of the item (not the key!), for instance "c" without the double quotes; if A points to a chain containing multiple items, just list them in alphabetical order by separating them with a comma and no spaces. For example, if A[ 2 ] points to a chain containing items a and b, fill the blank next to A[ 2 ] with "a,b" without the double quotes.
Hash Table Operations:Consider a hash table with 7 slots that uses chaining to resolve collisions. The hash function is h(x) = x mod 7. Show the structure of the hash table after inserting the following sequence of integers: {15, 22, 36, 7, 10, 42, 29}. Demonstrate the process of searching for the number 22 in the hash table.
