[Haskell] Re: How to substract a list?

In Haskell, ++ can spends second list argument onto the end of first list argument. How to substract the second list from the first list?

For example, [(5,1),(4,1),(3,1),(2,1),(1,1)] substract [(2,1),(1,1)] I want to get result list: [(5,1),(4,1),(3,1)]

Look at e.g. http://haskell.org/ghc/docs/latest/html/libraries/base/Data.List.html#v%3A%5... for inspiration Regards, Peter
