Problem Statement

Using two Arrays of equal length, create a Hash object where the elements from one array (the keys) are linked to the elements of the other (the values)

Let's start with the solution:

Step by Step solution about How to resolve the algorithm Hash from two arrays step by step in the Haskell programming language

The code snippet you provided creates a map from a list of keys to a list of values. The map is created using the fromList function, which takes a list of pairs and returns a map. In this case, the list of pairs is created by zipping the list of keys with the list of values.

The resulting map is assigned to the variable mymap. We can use the mymap variable to access the values in the map. For example, we can use the lookup function to get the value associated with a particular key.

Here is an example of how to use the mymap variable:

> lookup 'a' mymap
Just 1

This code looks up the value associated with the key 'a' in the mymap map. The result is a Just value, which contains the value 1.

We can also use the member function to check if a key is present in the map.

> member 'a' mymap
True

This code checks if the key 'a' is present in the mymap map. The result is True, which indicates that the key is present in the map.

Source code in the haskell programming language

import Data.Map

makeMap ks vs = fromList $ zip ks vs
mymap = makeMap ['a','b','c'] [1,2,3]
