Clustering string based on their length
<p>I have a list of strings like {abb, abgt,acctg,tgbs,abs} and so on. The number of strings is defined by user. I need to cluster the strings of similar length together. Which clustering algorithm will be suitable for such case and why?? As far I know K-means need to know number of clusters before hand which I cannot tell as number of string is not predefined.</p>
