Simple strings with identical hashcode
def alphabet = ('A'..'Z')+ ['Æ','Ø','Å']
def combinations = [:]
alphabet.each { first ->
alphabet.each { second ->
alphabet.each { third ->
def str = "" + first + second + third
def hash = str.hashCode()
if (combinations[hash]) {
println combinations[hash]+" has same hashcode as "+str+"!!!!!! ("+hash+")"
