While I'm sure the President doesn't research all laws he signs, Obama is somewhat tech savvy. [VIDEO] I wouldn't be surprised if he made the threat based on his own personal moral ideology.
Read original comment ↗Bubble sort is never a good choice unless so extremely lazy or what to impersonate Obama...[0] There are dual-pivot quicksort, smooth sort (in-place, based on Leonardo numbers and takes O(n) time to process a presorted array and O(n log n) in the worst case, and achieves nearly-linear performance on many nearly-sorted inputs), TimSort (that's stable as plus). Morealso changing stable to unstable sort is usually a very bad move. [0]: [VIDEO]
Read original comment ↗I get your point, but why would you pick bubble sort? That’s one any engineer should be able to implement without any help. It’s the more complex/useful ones worth discussing. Even Obama knows this: [VIDEO]
