Hash tables - open adressing for collision resolution
I have up to 10,000 such data:
I have to use a hash table with open adressing for collision resolution to store this data and retrieve them effectively, on the basis of the isbn.
char authors; // first and last names of the author
char title; // title of the publication
unsigned int year; // year of the publication
char isbn; // publication code
I'm having problems understanding how to store this data.
I can't figure out what is the key of the hash table here?
When does the collision happens?
Give me examples using this data please.
