Write a Perl program that uses a hash and a large number of operations on the hash. For example, the hash could store people's names and their ages. A random-number generator could be used to create three- character names and ages, which could be added to the hash. When a duplicate name was generated, it would cause an access to the hash but not add a new element. Rewrite the same program without using hashes. Compare the execution efficiency of the two. Compare the ease of programming and readability of the two.

- In class HashTable implement a hash table and consider the following:(i) Keys are integers (therefore also negative!) and should be stored in the tableint[] data.(ii) As a hash function take h(x) = (x · 701) mod 2000. The size of the table istherefore 2000. Be careful when computing the index of a negative key. Forexample, the index of the key x = −10 ish(−10) = (−7010) mod 2000 = (2000(−4) + 990) mod 2000 = 990.Hence, indices should be non-negative integers between 0 and 1999!(iii) Implement insert, which takes an integer and inserts it into a table. Themethod returns true, if the insertion is successful. If an element is already inthe table, the function insert should return false.(iv) Implement search, which takes an integer and finds it in the table. The methodreturns true, if the search is successful and false otherwise.(v) Implement delete, which takes an integer and deletes it form the table. Themethod returns true, if the deletion is successful and false otherwise.(vi)…

Write a c++ program to add two large integers with up to 300 digits. One approach is to treat each number as array, each of whose elements is a block of digits of that number. For example, the integer 179,534,672,198 might be stored as block[0] =198, block[1] = 672, block[2] = 534, block[3] = 179. Add the two integers (lists), element by element, carrying from one element to the next when necessary. NOTE: You don’t have to use string input for the numbers. {Hint: when does the extraction stop extracting characters from the input buffer? How does the get function work? What character is always placed in the input stream when you press enter } The user will input the numbers using the following format: User input is in bold and underlined. Enter the number using this format(###,###,###) up to 300 digits: 179,534,672,198 Enter the number using this format(###,###,###) up to 300 digits: 564,325 Addition Result: 179,535,236,523 Enter the number using this format(###,###,###) up to 300…

In this task, two hash tables should should be implemented. You can follow the followinginstructions:- In class HashTable implement a hash table and consider the following:(i) Keys are integers (therefore also negative!) and should be stored in the tableint[] data.(ii) As a hash function take h(x) = (x · 701) mod 2000. The size of the table istherefore 2000. Be careful when computing the index of a negative key. Forexample, the index of the key x = −10 ish(−10) = (−7010) mod 2000 = (2000(−4) + 990) mod 2000 = 990.Hence, indices should be non-negative integers between 0 and 1999!(iii) Implement insert, which takes an integer and inserts it into a table.
