4 12-2 Selection Sorts In each pass of the selection sort, the smallest element is selected from the unsorted sublist and exchanged with the element at the beginning of the unsorted list. We discuss two classic selection sorts, straight selection and heap sort.

21 12-3 Insertion Sorts In each pass of an insertion sort, one or more pieces of data are inserted into their correct location in an ordered list. In this section we study two insertion sorts: the straight insertion sort and the shell sort.

It concludes with a comprehensive example that demonstrates each operation.
