My second solution was:

This code = 60 bytes, but i get Run-Time error on SPOJ

I don't understand how this code can create RTE?

I think it's because getLine will try to read something even if you're at the end of the input. Try guarding the call with 'isEOF', e.g. main=isEOF>>=flip unless(getLine>>=print.(2^).length.filter(`elem`"TDLF")>>main) -- Frerich Raabe - raabe@froglogic.com www.froglogic.com - Multi-Platform GUI Testing
