compress string

Lets say I have a string as:
"abbabccbc". It has to be compressed so that it first will become "ababcbc", then becomes "abc". Similarly, "abcaab" will become "abcab" and but stays as it is after that.
in short first i compare single chars, then 2 chars and so on....
How can I do it efficiently?

What is the rule, exactly?
Do you repeatedly delete any repetition, whatever the length, as long as there is no other character in between?

adjacent subdtrings of any length that are same must be killed.
abcabc qould yield abc
abababcdcd-> abcd
aaaa->a
abbaccbd->abbacbd
and so on...
but abcdabc would remain as it as the d lies between the same substrings..
