haskell merge lists
To merge two lists in Haskell, you can use the ++
operator or the concat
function. The ++
operator concatenates two lists together, while the concat
function concatenates a list of lists into a single list.
Here is an example using the ++
operator:
mergeLists :: [a] -> [a] -> [a]
mergeLists [] ys = ys
mergeLists (x:xs) ys = x : mergeLists xs ys
And here is an example using the concat
function:
mergeLists :: [[a]] -> [a]
mergeLists = concat
In the first example, the mergeLists
function takes two lists as input and recursively merges them together by appending the first list to the second list.
In the second example, the mergeLists
function takes a list of lists as input and uses the concat
function to merge them into a single list.
You can use either of these functions depending on your specific requirements.
