I have a text file that looks like this 
1ct9B 3 1
1f7uA 2 3
1gaxA 2 1
1gpmA 3 5
1ihoA 6 4
1mopA 6 3
1ileA 2 5
1iq0A 2 3
1vlhB 5 3
1jhdA 5 4
etc ...

The first column contains an 'item' the second column contains a 'group number' and the third item is a count. What I need to do is, for every group, retrieve the item that has the largest count. So, for the data above, the results for each group would be: 
1ileA 2 5
1gpmA 3 5
1jhdA 5 4
1ihoA 6 4

I'm sure this is a very simple task, but I've not been able to work out how to do it so far. I've just created lots of hashes and not really got anywhere. All help/advice much appreciated.
