+Run-length encoding is a simple data compression technique that can be effective 
+when repeated values occur at adjacent positions within a list. 
+
+Compression is achieved by replacing groups of repeated values with one copy of the value, 
+followed by the number of times that it should be repeated.   
+For example, the list  
+`["A", "A", "A", "A", "A", "A", "A", "A", "A", "A", "A", "A", "B", "B", "B","B","A","A","A","A","A","A","B"]`  
+would be compressed as `["A",12,"B",4,"A",6,"B",1]`. 
+
+Decompression is performed by replicating each value in the list the number of times indicated.
+
+Write a recursive function that decompresses a run-length encoded list. 
+Your recursive function will take a run-length compressed list as its only argument. 
+It will return the decompressed list as its only result. 
+
+Create a main program that displays a run-length encoded list and the result of decoding it.

+# **Cataloger of Household elements 🏡**
+
+This project is to develop a household element cataloger, 
+a tool that helps users catalog and manage elements in their homes.   
+The cataloger will use recursion to explore home environments in depth, gathering information about elements, 
+such as name, location, and category.   
+It will also provide functionality to search, add, edit, and delete elements from the catalog, 
+simplifying home inventory management.
+
+
+## **elementive 🎯**
+The goal of the project is to provide users with a practical tool for cataloging and keeping
+track of elements in their home.   
+Using variables, strings, mathematical calculations, conditional operators, loops, functions, arrays, JSON elements, 
+and recursive functions, the cataloger will enable users to effectively organize their household elements 
+and obtain detailed information about them.
+
+## **Recursive exploration of home environments 🔁**
+
+- Using a recursive function, explore home environments, such as rooms and closets, to identify the elements present.  
+- Gather information about elements, such as name, location, and category.
+- Use an appropriate data structure, such as an array of JSON elements, to store element information.
+
+## **Adding new elements ➕**
+
+- Using a function, allow the user to add new elements to the catalog.
+- Capture the element's information, such as name, location, and category, and create a new JSON element with that information.
+- Add the element to the home element catalog.
+
+## **Modify existing elements ✍️**
+
+- Using a recursive function, allow the user to search and edit existing elements in the catalog.
+- Allow the user to edit the element's information, such as name, location, or category.
+- Update the corresponding JSON element in the catalog with the new information.
+
+
+## **element deletion ➖**
+
+- Using a recursive function, allow the user to search for and delete existing elements in the catalog.
+- Remove the corresponding JSON element from the home element catalog.
+
+## **Limitations ✋**
+
+- The project focuses on cataloging and management of household elements, without including features such as element 
+  quantity management or integration with more complex inventory systems.
+- Interactions with external databases or other sources of additional information are not considered.
+
+## **Project Duration ⏲️**
+
+Considering the functionality required and the use of the specified constructs, 
+the project is expected to take about 1 to 2 days to complete.
