Above is the partial implementation of the double hashing technique used for hash tables. Now, you are expected to perform the following tasks and modify the above implementation for the separate chaining technique. Just give the code for the below tasks. 1. Create a list array. a. Use the list container class from the standard library. 2. Re-write the constructor to initialize the list array. a. The constructor needs to receive the array size as an argument. 3. Re-write the code for the insert function so that it works for the separate chaining technique. a. Use hash1 for the separate chaining. b. Use list's push_back function
