/* ALGORITHM
1. Start from left hand side
2. Compare first two numbers
3. If first_number > second_number than swap both number position. And if first_number < second_number than these compare next two numbers i.e. second_number and third_number.
4. Step-3 process repeat until there are no more numbers left to compared.
