Introduction
Sorting is ordering a list of objects. We can distinguish two types of sorting. If the number of objects is small enough to fits into the main memory, sorting is called internal sorting. If the number of objects is so large that some of them reside on external storage during the sort, it is called external sorting. In this chapter we consider the following internal sorting algorithms

1. Selection Sort
2. Bubble Sort
3. Bucket Sort
4. Heap Sort
5. Inserting Sort
6. Merge Sort
