Sorting

Sorting. Pseudocode of Insertion Sort. Insertion Sort. To sort array A[0.. n -1], sort A[0.. n -2] recursively and then insert A[ n -1] in its proper place among the sorted A[0.. n -2] Usually implemented bottom up (nonrecursively) Example: Sort 6, 4, 1, 8, 5 6 | 4 1 8 5

Heap Sort

Heap Sort. The idea : build a heap containing the elements to be sorted, then remove them in order. Let n be the size of the heap, and m be the number of elements to be sorted. The following two steps implement heap sort: Step1 : Construct the heap by doing m insertItem operations.
