Can anyone help me do this hash table program? I just need the program. plz give me a right answer. thx.

Hash table collision algorithm analysis

In this project, you need to build a hash table using two different algorithms for collision resolution that we discussed in lecture open addressing and chaining. Your hash table should be build from the provided data set on Moodle called playerData. You also need to evaluate the performance of each algorithm in terms of how many collisions are generated while the table is built and the operations required to retrieve data from the table. Your evaluation and the results need to be described in a 2 - 3 page paper, single-spaced, 12pt. Times New Roman font.

Assignment data if you need the data plz leave your email, because this file is a little big. I cannot copy and post here.

There is a file on Moodle called playerData that includes every Major League Baseball player on every team since 1985. For example, the first two rows in the file show the header row, which shows what each column includes, and the first row of data. The first row of data is:

1985, ATL, NL, barkele01, 870000, Len, Barker, 1955, USA, 225, 77, R, R

The fields in the header row show:

yearID year, between 1985 and 2016

teamID three-letter abbreviation for team

leagueID league that the team belongs to, either National League (NL) or American League (AL)

playerID ID for the player, used in the Lahman database where I downloaded data

salary how much money the player made that year

firstName players first name

lastName players last name

birthYear year the player was born

birthCountry country where the player was born

weight players weight

height players height

bats how the player bats, either right (R ) or left (L) handed, or switch (S).

throws how the player throws, either right (R ) or left (L) handed.

Assignment requirements

Build hash table You need to process the data provided and build a hash table, where the key for entries in the hash table is the players first and last name, concatenated. For example, for the first row in the file, the key would be LenBarker. For a hash function, you can use the hashSum function discussed in lecture, or any other hash function that you want to try. In your project report, describe the hash function that you use. Each player should only appear in the hash table one time. Each record in the hash table needs to include the players information, including first and last name, birth year and country, height and weight, and batting and throwing. Each record also needs to include a list of all the teams and years that the player was active, and their salary for that year. For example, the hash table entry for Len Barker would be:

First name: Len

Last name: Barker

Year born: 1955

Country born: USA

Weight: 225

Height: 77

Bats: R

Throws: R

Teams and salary: 1985, ATL, NL, 870000

1986, ATL, NL, 880000

1987, ATL, NL, 890000

1987, ML4, AL, 72500

1988, ATL, NL, 900000

The teams and salary entries are taken from the playerData file for every row where the players name appears. Note: you could have multiple players with the same name. You will need some method for verifying the uniqueness of a player. For example, if there were another Len Barker in the data file, you might want to check the height and weight or year born information to determine if its the same person.

Set hash table size using command line argument

Use a command line argument to set the size of the hash table. There are 5072 unique players in the playerData file. Run your program multiple times, using 5072 as the minimum hash table size, and increase the size of the hash table up to 15K- 20K. In your project write up, describe the effect that increasing the hash table size had on the number of collisions for both algorithms.

Collision analysis

As part of this assignment, you need to evaluate the performance of two collision resolution algorithms open addressing and chaining. My suggestion for approaching this problem is to build two hash tables as you are reading the data from the file one hash table resolves collisions using open addressing and the other hash table resolves collisions using chaining.

Collisions during building the table

As you are building the hash table, you need to count the number of collisions that each collision resolution algorithm generates. You also need to count the number of search operations needed to find a location for the record. For example, if you are using chaining and there is a collision and you traverse three records in a linked list to find an open location, then the number of search operations is 3. If you get a collision using open addressing and evaluate 4 entries in the hash table before finding an open location, then the number of search operations is 4. Once the table is built, display the following information clearly for the user:

Hash table size:

Collisions using open addressing:

Collisions using chaining:

Search operations using open addressing:

Search operations using chaining:

User input

Your program needs to present the user with the option of looking up a player in the hash table. A suggested menu is as follows:

1. Query hash table

2. Quit program

If the user selects Query hash table, they should be asked to input the name of a player. If the player is in the hash table, display the record for that player, including all of the information shown on the previous page for the Len Barker example. If the player is not in the hash table, display Player not found, and display the menu again so the user can select another player or quit the program.

Linear searches needed to retrieve data

In addition to displaying player information, your program should also display the number of search operations needed to find the player in the hash table for both open addressing and chaining. For example, if the hash code for a player is 0, and no other players are stored at that index, then there would be zero searches needed to find the players information. However, if there are 5 players with the same hash code, and the player you need was stored at the end of the linked list for that index using chaining, then the number of searches is 5.

Display the following information, in addition to the player information:

Search operations using open addressing:

Search operations using chaining:
