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 What index has the most occurrence of collisions?
