Heap ComplexityThe part just shown very similar to removal from a heap which is O(log(n)). You do it n-1 times so it is O(nlog(n)). The last steps are cheaper but for the reverse reason from the building of the heap, most are log(n) so it is O(nlog(n)) overall for this part. The build part was O(n) so it does not dominate. For the whole heap sort you get O(nlog(n)).There is no extra memory except a few for local temporaries.Thus, we have finally achieved a comparison sort that uses no extra memory ...

Complexity Analysis of Bubble SortingIn Bubble Sort, n-1 comparisons will be done in 1st pass, n-2 in 2nd pass, n-3 in 3rd pass and so on. So the total number of comparisons will be(n-1)+(n-2)+(n-3)+.....+3+2+1Sum = n(n-1)/2i.e O(n2)Hence the complexity of Bubble Sort is O(n2).The main advantage of Bubble Sort is the simplicity of the algorithm.Space complexity for Bubble Sort is O(1), because only single additional memory space is required for temp variableBest-case Time Complexity ...
We assume that we're sorting a total of nn elements in the entire array.The divide step takes constant time, regardless of the subarray size. After all, the divide step just computes the midpoint qq of the indices pp and rr. Recall that in big-Θ notation, we indicate constant time by \Theta(1)Θ(1).The conquer step, where we recursively sort two subarrays ...
