Write a class, MyHashTable to implement a hash table that uses Open Hashing, and insert it in a test prosram The hash table efficiently stores records and uses character strings as loeys. The member functions will be: MyHashTable(int sz) boolean inaert(String key, String record): // returns fale if key is present, true othervise // create an enpty has table of fixed size sz // key is a string of lover case alpbabetic chars /o spaces String isPresent (String key)/ returns the record if key is present, null othervise boolean delete(String key) returns false if key is not present, true othervise int senberahsp; void listall I/ returns the nunberof recorda in the data structure // list a11 embers of the hash table in the order that I/ they are stored. Precede each one with an integer giving // the index in the table of that record The hash function MUST BE as follows: int hash(String k, int tableSize) int ky.lengthO int aus-0 for(int i-1:i 0:1-- /I use unsigsed ints in c/c sun .,un.31 + (int) (ky.charkt(i)); sun sun &0x7fffffff: return sum % tableSize; // automatically applies nod 2.(32) // remove the sign bit // % works fine with a positive dividend Your program will read a text file from System.in that contains text commands. In response to each command your program will output one or more lines of text to System.out.
