So in the end you'd have either an O (1) + O (n) + O (nlogn) = O (nlogn) for the build heap method, and an O (nlogn) + O (nlogn) = O (nlogn) for the insertion method. mattress bed bugs pics

"Web10 de jul. de 2024 · For heapsort, the worst-case is still Θ (n * logn) . For quicksort, the worst-case complexity is Θ (n^2). As mentioned before, the worst-case occurs when partitioning is always completely unbalanced. An example that causes quicksort to run in Θ (n^2) is when the array is already ordered.
