Try pattern matching on the list head and tail as in (x:xs). Take a look at the source code for filter [1], which can be put to use here.

I have a tuple with three values and i want to remove the tuple which contains a particular name.

So d = (name, month, date) i take a user input of name and then search the list which has tuples of the above declared type. Which ever tuple has the name it should be deleted from the list.

d is the tuple. db should be a list of tuples.

remove :: (Eq) => IO String -> d print "Enter the name to be removed” a <- getLine remove x [] = [] print “Record not found” remove x db = if x ==

Please let me know!

Thanks a lot
