### BUBBLE Sort

    ### MAKE COPY OF ORIGINAL LIST ###
    original_list = list_to_sort[:]

    swapped = True

    while swapped:
        swapped = False

            if unsorted[i] > unsorted[i+1]:
                unsorted[i], unsorted[i+1] = unsorted[i+1], unsorted[i]
                swapped = True



### MERGE Sort

        else:
            list_sorted.append(list_b.pop(0))
    if len(list_a) < 1:
        list_sorted += list_b
    else:
        list_sorted += list_a
    return list_sorted


def merge_sort(unsorted):
    if len(unsorted) <= 1:
        return unsorted
    else:
        middle = len(unsorted) // 2 # rounding down if the list has an odd number of items
        front = unsorted[:middle]
        back = unsorted[middle:]
        front = merge_sort(front)
        back = merge_sort(back)
    return merge(front, back)


#Generate a large (10 items) random list
list_to_sort = [randint(0,100000) for i in range(1000)]

#Create anonymous functions to use with timeit, be sure to check these function names match your pasted ones
bs = lambda: bubble_sort(list_to_sort)
ms = lambda: merge_sort(list_to_sort)

#time the functions for 100 runs each

print("Merge took:")
print(timeit(ms, number = 100))

print("Bubble took:")
print(timeit(bs, number = 100))
