Thanks. • Each functionality component must be implemented as a separate function, though the function does not need to be declared and defined separately • No global variables are allowed • No separate.hor.hpp are allowed • You may not use any of the hash tables, or hashing functions provided by the STL or Boost library to implement your hash table • Appropriate, informative messages must be provided for prompts and outputs You must implement a hash table using the Double Hashing collision strategy and the mid-square base 10 hashing function with an R of 2.
