Exams - Ewoks Fans

/* You have a list of birthdays. People born on 25.05.1973 and after are fans of Ewoks and these before that
 – haters. The biggest hater is the oldest person born before 25.05.1973. The biggest fan is the youngest person
 born after 25.05.1973. Find the biggest fan and hater of Ewoks. Exclude people born on or before 01.01.1900 and
 those born on and after 01.01.2015, because most of them are either dead or not born yet.
 The input data comes as array of strings containing dates in the format “dd.mm.yyyy”.
 Print at the console when the biggest fan and the biggest hater of Ewoks were born.
 Use the method "date.toDateString()" to format the date at the output.
 If there is only one fan or hater, print out the date of his birth. If there are no people between 01.01.1900
 and 01.01.2015 print “No result”. */
