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
