Question

Task 2. Instead of using the default hashCode method to each key, create a hash function applying the folding method.

Within your hash function

          Split the string into 3 sub-strings, based from the reg-ex "-"

          Parse your sub-strings to Integer and add (folding method)

          Parse the summed value to String

          Initialize an int variable for your hash to 0

          Loop to each character index of the String

                    Apply the general formula for hashing: hash=31*hash+character in that index position; 

          Append & 0xFFFFFFF to it to make the resulting hash positive

Convert the hash to index of tablesize=20 using the % operator

          Return hash
