# 7. Flatten a Nested List Structure ???
 - what is nested list structure 
    A nested structure is when we have a structure within a similar structure.
      Eg: List[List[1,2,3], List[4,5,6]] is a nested structure. 
        Because there are lists within a list. i.e Similiar structure within it. 
 - what is flattening 
   Flattening is converting a nested structure to a not nested structure, that is collapsing a list of lists to a list
    Eg: Converting List[List[1,2,3], List[4,5,6]] to List[1,2,3,4,5,6]
 - how to Flatten a Nested List Structure ???
    We can do that by removing the nested ness of the strucure
