Nettet17. sep. 2014 · Any comparison-based sorting algorithm requires at least Ω(nlgn) comparisons in the worst case. Some require even more than that. Slightly more formally: Observe that the Ω-notation is already defined to mean "at least," so, really, you don't have to say it. Saying "at least Ω(nlgn)" is redundant, like saying "ATM machine" or "PIN … Nettet5. jun. 2024 · You are confusing time and space complexity.

While it is correct that your algorithm in the end will only have n/2 iterations (because it makes 2 lookups in one iteration) it will again yield n-lookups. food in weslaco tx

"Nettet26. okt. 2012 · Sorting is one of those subjects where, as they say, the devil is in the details. Typically, secondary considerations dominate the performance input parameters. However, if comparisons are very expensive and if most keys are identical, it is possible that the input could be considered already sorted or already almost sorted.
