Solve Exercise P15.4 in your textbook. Read the file from System.in and write all strings with the same hash code to System.out, in the format

hashcode1: string1, string2 ...
hashcode2: string3, string4, string 5, ...
...

Print hash codes and strings in sorted order.

Draft: Just print out the hash code for each word in the input, in the format

hashcode1: string1
hashcode2: string2
