In Absurdistan, there are n towns (numbered 1 through n) and m bidirectional railways. There is also an absurdly simple road network — for each pair of different towns x and y, there is a bidirectional road between towns x and y if and only if there is no railway between them. Travelling to a different town using one r...

In Absurdistan, there are n towns (numbered 1 through n) and m bidirectional railways. There is also an absurdly simple road network — for each pair of different towns x and y, there is a bidirectional road between towns x and y if and only if there is no railway between them.

NoteIn the first sample test sequence of removing made by Nastya looks like this:"ababcba" "ababcba" "ababcba" "ababcba" Nastya can not continue, because it is impossible to get word "abb" from word "ababcba".So, Nastya will remove only three letters.
