Implement the Merge Sort Algorithm - Step 21

Tell us what’s happening:

I thought it would be simple but somehow I must be doing something wrong without noticing. Can you please give me a hint as to what is wrong here?

Your code so far

def merge_sort(array):
    if len(array) <= 1:
        return
   
    middle_point = len(array) // 2
    left_part = array[:middle_point]
    right_part = array[middle_point:]

    merge_sort(left_part)
    merge_sort(right_part)

    left_array_index = 0
    right_array_index = 0
    sorted_index = 0

    while left_array_index < len(left_part) and right_array_index < len(right_part):
        if left_part[left_array_index] < right_part[right_array_index]:
            array[sorted_index] = left_part[left_array_index]
            left_array_index += 1
        else:
            array[sorted_index] = right_part[right_array_index]
            right_array_index += 1
        sorted_index += 1

    while left_array_index < len(left_part):
        array[sorted_index] = left_part[left_array_index]
        left_array_index += 1
        sorted_index += 1
   
    while right_array_index < len(right_part):
        array[sorted_index] = right_part[right_array_index]
        right_array_index += 1
        sorted_index += 1

I found the solution. Sorry for disturbing.
