合并Haskell中的两个列表 [英] Merging two lists in Haskell

问题描述

不知道如何在Haskell中以如下方式合并两个列表：

  INPUT：[1,2,3,4,5] [11,12,13,14] 
 
输出：[1,11,2,12,3,13,4,14， 5] 
  

解决方案

  merge :: [a]  - > [a]  - > [a] 
合并xs [] = xs 
 merge [] ys = ys 
 merge（x：xs）（y：ys）= x：y：合并xs ys 
  

Can't figure out how to merge two lists in the following way in Haskell:

INPUT:  [1,2,3,4,5] [11,12,13,14]

OUTPUT: [1,11,2,12,3,13,4,14,5]

解决方案

merge :: [a] -> [a] -> [a]
merge xs     []     = xs
merge []     ys     = ys
merge (x:xs) (y:ys) = x : y : merge xs ys
