[Haskell-beginners] how more efficient read/write a file ?

[Benjamin Edwards]

You should look up bytestring and friends on hackage.

If it is something quite simple you can use the lazy variants and provided
that you don't try to hold onto the input you should get nice constant space
without trying too hard.

I recommend the early chapters on IO in real world haskell if you want more
info on lazy IO.

just like 010 to 101( XOR bits ) , is it some efficient function down it ?
