This will **dramatically improve** performance for all but tiny arrays. --- code_to_optimize/bubble_sort.py | 8 ++------ 1 file changed, 2 insertions(+), 6 deletions(-) diff --git a/code_to_optimize/bubble_sort.py b/code_to_optimize/bubble_sort.py index 9e97f63a0..19b6ee04a 100644 --- a/code_to_optimize/bubble_sort.py +++ b/code_to_optimize/bubble_sort.py @@ -1,10 +1,6 @@ def sorter(arr): print("codeflash stdout: Sorting list") - for i in range(len(arr)): - for j in range(len(arr) - 1): - if arr[j] > arr[j + 1]: - temp = arr[j] - arr[j] = arr[j + 1] - arr[j + 1] = temp + # Use Python's highly optimized built-in sorting method (Timsort) + arr.sort() print(f"result: {arr}") return arr
