Hash Search Design a hash table which the phone number is the key word and can be used to do search. The phone number is looked on as key and thus the hash function should be designed based on it. Basic Requirements 1) Each record contains 3 data items, i.e. name, sex and phone number. 2) Read the datum from txt file, use phone number as the key to design hash function, using open addressing method to solve conflicts. Build hash table and show highest number of hashes. There are 450 records in total, and the size of hash table is defined as 467. The maximum number of hashes is required to be no more than 80 3) When the user input a phone number, your program should do hash search based on this number. If the number dose exist then the corresponding information should be shown, and the number of hashes should be shown as well. If the number does not exist in the table, still show the number of hashes and the information My data LiuJing Female 13814231733 WangAnqi Male 15855129526…
