Heap sort algorithm gfg
Web12 de nov. de 2024 · The time required to merge in a merge sort is counterbalanced by the time required to build the heap in heapsort. The merge sort requires additional space. The heapsort may be implemented using additional space, but does not require it. Heapsort, however, is unstable, in that it doesn't guarantee to leave 'equal' elements unchanged. WebA (n) are all leaves. * here n is the length of heap (heap size). * Any index after (n/2) will have left (i) and right (i) greater than n. * Also parent for a given index i is floor of i/2. // Go from the bottom non-leaf nodes of the binary tree, hence i--. // The max non-leaf nodes of a binary tree with n nodes is n/2.
