Please code in OCaml language
I have a type person that has a name (string), age (int), and hobbies (a list of strings).
And I have a type database (db) with a list of person
How would I implement a program for remove?
For example: if my database has the list of person
db1 = { database = [ {name = "Sidonie"; age = 20; hobbies = ["Gaming"]}; {name = "Ryan"; age = 18; hobbies = ["Legos"; "Gaming"]}; {name = "Arnold"; age = 34; hobbies = ["Skiing"; "Cooking"]}; {name = "Alice"; age = 25; hobbies = ["Gaming"; "jogging"]} ] }
How could I implement a remove "Alice" db1 where all instances of a person named "Alice" is removed (if there are two "Alice"s then both of them are removed, etc).
Or would I have to change how my database stores person information? You can use recursion and List library modules as well.
typeperson={name:string;age:int;hobbies:stringlist} type database ={db : person list } remove name database: - Type: person dbdb - Description: given a person's name and a database, remove all persons with the same name from the database and return the updated database. If no persons exist in the database with the same name as the given person, the database should not change. - Examples: db1= remove "Alice" db1 (db1 no longer contains Alice, db1 is now empty )Step by Step Solution
