    This method returns the fruit name by getting the string at a specific index of the set.

    :param fruit_id: The id of the fruit to get
    :param fruits: The set of fruits to choose the id from
    :return: The string corrosponding to the index ``fruit_id``

    **This method is part of a series of debugging exercises.**
    **Each Python method of this series contains bug that needs to be found.**

    | ``1   It does not print the fruit at the correct index, why is the returned result wrong?``
    | ``2   How could this be fixed?``

    This example demonstrates the issue:
    name1, name3 and name4 are expected to correspond to the strings at the indices 1, 3, and 4:
    'orange', 'kiwi' and 'strawberry'..

#it used dictionary/set instead of list(using []) and sorting option for set and dictionary is not the same as list  
# The issue with the code is that sets are unordered collections of unique elements, 
# meaning that the order of elements in a set is not guaranteed. 
# To fix the issue, modify the function to take a list instead of a set as input. 
# Lists are ordered collections of elements, meaning that the order of elements is preserved
