Define a recursive function merge :: Ord a => [a] => [a] => [a] chat merges two sorted lists of values to give a single sorted list. For example: > merge [2,5,6] [1,3,4] [1,2,3,4,5,6]

Question
Please can someone explain this recursive function
Solution
(a) The required haskell code is :
merge [] x = x
merge x [] = x
merge (x:xs) (y:ys)|
x< y = x:merge xs (y:ys) |
otherwise = y:merge (x:xs)ys
Transcribed Image Text:Solution (a) The required haskell code is : merge [] x = x merge x [] = x merge (x:xs) (y:ys)| x< y = x:merge xs (y:ys) | otherwise = y:merge (x:xs)ys
2. Define a recursive function
merge Ord a => [a] -> [a] -> [a]
that merges two sorted lists of values to give a single sorted list.
For example:
> merge [2,5,6] [1,3,4]
[1,2,3,4,5,6]
