Write a function to sort an array of objects by a specific property value.

Sort an array of objects by a specific property value:

To sort an array of objects by a specific property value, you can use a sorting algorithm such as the merge sort or quicksort.

Here's an example function in Python that sorts an array of objects by a given property value:

def sort_objects_by_property(array, property_name):

    # Define the sorting key function

    def get_property_value(obj):

        return getattr(obj, property_name)

    # Recursive function for merge sort

    def merge_sort(arr):

        if len(arr) <= 1:

            return arr

        mid = len(arr) // 2

        left = arr[:mid]

        right = arr[mid:]

        left = merge_sort(left)

        right = merge_sort(right)

        return merge(left, right)

    # Merge function for merge sort

    def merge(left, right):

        merged = []

        i = j = 0

        while i < len(left) and j < len(right):

            if get_property_value(left[i]) <=

get_property_value(right[j]):

                merged.append(left[i])

                i += 1

            else:

                merged.append(right[j])

                j += 1

        while i < len(left):

            merged.append(left[i])

            i += 1

        while j < len(right):

            merged.append(right[j])

            j += 1

        return merged

    # Call the merge sort function

    return merge_sort(array)

Explanation:

1. The sort_objects_by_property function takes two parameters: array, which is the array of objects to be sorted, and property_name, which specifies the property to sort by.

2. Inside the sort_objects_by_property function, we define a nested function get_property_value that retrieves the value of the specified property for a given object. We use the getattr function to dynamically get the property value using its name.

3. The merge_sort function is a recursive implementation of the merge sort algorithm. It splits the array into two halves, recursively sorts each half, and then merges them together in sorted order.

4. The merge function is a helper function for the merge sort algorithm. It takes two sorted arrays (left and right) and merges them together in sorted order.

5. In the main body of the sort_objects_by_property function, we call the merge_sort function with the array parameter and return the sorted array.

By using this sort_objects_by_property function and specifying the desired property name, you can sort an array of objects by that property value.
