Print all subsets for a string

Use java.util.LinkedList to print out all subsets for a giving string. Use CState.java.

For a given string abcdef, list out all possible nonempty subset string of

abcdef using Queue data structure.

For example: a,ab,b,abc,ac,bc, etc.

public class CState {

private String Prefix = new String(); private String Suffix = new String(); public CState (String Pre, String Suff) { Prefix = Pre; Suffix = Suff; } public String pre() { return Prefix; } public String suff() { return Suffix; } }
