You need two methods : 1: to validate the string that if it passes the case (it should not have repeated chars) 2: delete chars here create a arraylist and insert all the string char in it and iterate over arraylist whenever a continuous two elements found , delete its all the occurrence from arraylist by get() method and remove() by passing index and at the end of string validate it. The usual way to decode variable length prefixes is by using a binary-tree. Don't feel forced to do it, we will have the utmost respect for all of our users, as using our page is the biggest contribution, anyway.
