Write the lines of code to insert the key (book's ISBN) and value ("book") pair into "my_hash_table". struct insert_into_hash_table {// Function takes a constant Book as a parameter, inserts that book indexed by// the book's ISBN into a hash table, and returns nothing.void operator()(const Book& book) {// Write the lines of code to insert the key (book's ISBN) and value// ("book") pair into "my_hash_table".}std::unordered_map& my_hash_table;};

It is solved in the next step:struct insert_into_hash_table { void operator()(const Book& book) { std::string ISBN = ""; // Write the variable for book's ISBN from the "book.hpp" file. if(my_hash_table.find(ISBN) == my_hash_table.end()) { // case when the ISBN is not present in the hash table. my_hash_table[ISBN] = book; } else { return; }
