     A hint for the future: When you're printing string values
for debugging purposes, print something that will make their
endpoints visible even if there's leading or trailing space.
For example, instead of the original

	System.out.println("Best :"+best[i]);
	System.out.println("Found "+found[j]);

you could try something like

	System.out.println("Best: <" + best[i] + ">");
	System.out.println("Found <" + found[j] + ">");

so that the output

	Best: <17601089>
	Found < 17601089>

would reveal the discrepancy more clearly.
