WEBISL - Web islands
For a given set of web pages, we want to find largest subsets such that from every page in a subset you can follow links to any other page in the same subset.
On the first line, there are two numbers, number of the pages N, and total number of links M. Pages are numbered from 0 up to N-1. On lines 2 up to M+1, there are two numbers per line. The first is the source page and the second is the target page of a link.
On N lines there is a component ID for every single page. The componet ID is the smallest page index on the component.
