Task 1: HardCode a C Hash Table that Will Accept a Key as String and Map to String Value. First Name Jane" "John" "Susan" Last Name "Smith" "Do" "Collins" "Rodgers" Jones" "Wright" "Bader" "Eric" "Mike" Create Methods to Insert: insert(key, value) insert("First", "Last") Findvalue("First")-> Method will return value Delete("First") - Method will delete key and value
