π Compare
The function that removes all repeating elements, I code four methods, and made a comparison.
The array:
arr = [1, 1, 2, 5, 3, 1, 1, 2, 5, 3, 1, 1, 2, 5, 3, 1, 1, 2, 5, 3, 1, 1, 2, 5, 3, 1, 1, 2, 5, 3, 1, 1, 2, 5, 3]

The results:
By comparison, it can be seen that the performance of filter()
is better, so the function adopts the filter()
.
