The running time of the heap sort algorithm is O(n log n), where n is the number of elements in the input array.
The running time of the heap sort algorithm is O(n log n) in terms of time complexity.
The time complexity of the heap sort algorithm is O(n log n), where n is the number of elements in the input array.
The worst-case time complexity of the heap sort algorithm is O(n log n), where n is the number of elements in the input array.
The best case scenario for the performance of the heap sort algorithm is when the input data is already in a perfect heap structure, resulting in a time complexity of O(n log n).
The running time of the bubble sort algorithm is O(n2), where n is the number of elements in the array being sorted.

The worst case scenario for the Heap Sort algorithm is O(n log n) time complexity, which means it can be slower than other sorting algorithms like Quick Sort or Merge Sort in certain situations. This is because Heap Sort requires more comparisons and swaps to rearrange the elements in the heap structure.
The running time of the radix sort algorithm is O(nk), where n is the number of elements to be sorted and k is the number of digits in the largest element.
The heap sort algorithm is as follows: 1. Call the build_max_heap() function. 2. Swap the first and last elements of the max heap. 3. Reduce the heap by one element (elements that follow the heap are in sorted order). 4. Call the sift_down() function. 5. Goto step 2 unless the heap has one element. The build_max_heap() function creates the max heap and takes linear time, O(n). The sift_down() function moves the first element in the heap into its correct index, thus restoring the max heap property. This takes O(log(n)) and is called n times, so takes O(n * log(n)). The complete algorithm therefore equates to O(n + n * log(n)). If you start with a max heap rather than an unsorted array, there will be no difference in the runtime because the build_max_heap() function will still take O(n) time to complete. However, the mere fact you are starting with a max heap means you must have built that heap prior to calling the heap sort algorithm, so you've actually increased the overall runtime by an extra O(n), thus taking O(2n * log(n)) in total.
The time complexity of an algorithm with a running time of nlogn is O(nlogn).
The running time of the algorithm being used for this task refers to the amount of time it takes for the algorithm to complete its operations. It is a measure of how efficient the algorithm is in solving the task at hand.
Finding a time complexity for an algorithm is better than measuring the actual running time for a few reasons: # Time complexity is unaffected by outside factors; running time is determined as much by other running processes as by algorithm efficiency. # Time complexity describes how an algorithm will scale; running time can only describe how one particular set of inputs will cause the algorithm to perform. Note that there are downsides to time complexity measurements: # Users/clients do not care about how efficient your algorithm is, only how fast it seems to run. # Time complexity is ambiguous; two different O(n2) sort algorithms can have vastly different run times for the same data. # Time complexity ignores any constant-time parts of an algorithm. A O(n) algorithm could, in theory, have a constant ten second section, which isn't normally shown in big-o notation.
