WA in ACMAKER

HI,

I am getting WA in ACMAKER. I tried for all the testcases I can think of, but dont know where I am going wrong. Can someone please give me some testcases where the result is wrong?

I am using dp. I first truncate insignificant words and then proceed using dp. Complete code is given below:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.Map;
import java.util.StringTokenizer;
public class ACMAKER {
    public static void main(String[] args) throws NumberFormatException, IOException {
	BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
	int insignificantWordLength = Integer.parseInt(br.readLine());
	
	while(insignificantWordLength > 0){
		String[] insignificantWords = new String[insignificantWordLength];
		for(int i=0;i<insignificantWordLength;i++){
			insignificantWords[i] = br.readLine();
		}
		
		String inputStr = br.readLine();
		while(!inputStr.equals("LAST CASE")){
			StringTokenizer stz = new StringTokenizer(inputStr);
			String originalAbbr = stz.nextToken();
			String abbr = originalAbbr.toLowerCase();
			
			String validWord = "";
			ArrayList<Integer> wordMarker = new ArrayList<Integer>();
			Map<Integer, Integer> wordLengthDict = new HashMap<Integer, Integer>();
			int wordCount = 0;
			int totalWordLength = 0;
			
			while(stz.hasMoreTokens()){
				String s = stz.nextToken();
				if(!HasWord(insignificantWords, s)){
					int currentWordLength = s.length();
					validWord += s;
					markWord(wordMarker, wordCount, currentWordLength);
					totalWordLength += currentWordLength;
					wordLengthDict.put(wordCount,totalWordLength);
					wordCount++;
				}
			}				
			//System.out.println(validWord);
			//System.out.println(wordMarker.toString());
			
			int abbrCount = getAbbrCount(validWord.toCharArray(), abbr.toCharArray(), wordMarker, wordLengthDict);
			if(abbrCount == 0){
				System.out.println(originalAbbr+" is not a valid abbreviation");
			}
			else{
				System.out.println(originalAbbr+" can be formed in "+abbrCount+" ways");
			}
			
			inputStr = br.readLine();
		}
		
		insignificantWordLength = Integer.parseInt(br.readLine());
	}

}

Thanks in advance.
