⚡️ Speed up function sorter
by 4211531.56 in PR #107 (temp
)
#248
Conversation
The function you provided, sorter, is already using Python's built-in sort function which has a time complexity of O(n log n), where n is a number of elements in the array. This is the fastest achievable sorting complexity for comparison-based sorts. However, if you want to achieve a marginal speed increase, writing this in-place might help. Here's an alternative version using list comprehension. Although this does not improve the time complexity, it gives a Pythonic touch: ```python def sorter(arr): return sorted(arr) ``` Again, this command returns a new sorted list and does not modify the original list. If you want to sort the list in-place, you only have the original function: Please note that sorting time complexity cannot be improved further than O(n log n) using comparison-based sorting algorithms. To really optimize this function, you would need a guarantee about the content of your data, for example, if your array only contained integers in a particular range, then you could use counting sort or radix sort, which can have a time complexity of O(n).

📄 4211531.56 (42115.32) speedup for sorter

⏱️ Runtime : 1070554.63

📝 Explanation and details
The function you provided, sorter, is already using Python's built-in sort function which has a time complexity of O(n log n), where n is a number of elements in the array. This is the fastest achievable sorting complexity for comparison-based sorts.
However, if you want to achieve a marginal speed increase, writing this in-place might help.
Here's an alternative version using list comprehension. Although this does not improve the time complexity, it gives a Pythonic touch:
def sorter(arr):
return sorted(arr)
Again, this command returns a new sorted list and does not modify the original list. If you want to sort the list in-place, you only have the original function:
Please note that sorting time complexity cannot be improved further than O(n log n) using comparison-based sorting algorithms. To really optimize this function, you would need a guarantee about the content of your data, for example, if your array only contained integers in a particular range, then you could use counting sort or radix sort, which can have a time complexity of O(n).

If you want to sort the list in-place, you only have the original function: Please note that sorting time complexity cannot be improved further than O(n log n) using comparison-based sorting algorithms. To really optimize this function, you would need a guarantee about the content of your data, for example, if your array only contained integers in a particular range, then you could use counting sort or radix sort, which can have a time complexity of O(n).
