| Mar 1, 2021 at 3:32 | comment | added | Pitouli | I confirm my suspicion. I updated the test bench so the array is parsed from an unmodified json. Obviously, every test is a bit slower, but it does not impact the ranking. And the K test is significantly slower than the C, D, L & M tests (on Mac Chrome). jsbench.me/mpklq0sj6l/1 | |
| Mar 1, 2021 at 3:12 | comment | added | Pitouli | @KamilKiełczewski : Careful! I have a strong suspicion that there is a bug in the test. When you add a console.log with the length of the arrays, you observe that the length is 0 in most cases. It feels like the array is not correctly reset between each run. And then of course, merging two null array is a very fast operation ;) This seems to be confirmed by this answer stackoverflow.com/a/66129415/2137476 where the K solution is fast, but less than the C solution (careful ; only look at the % comparaison; there is an error in the snippet and the chrono is wrong) | |
